A guide to online data plotting

 

When you’re dealing with complex data, visualization tools can help you simplify it and, more importantly, spot key trends and gain new insights

Sales figures, consumer behaviour and market research – the work we do often involves understanding and communicating a lot of complex information. To make good decisions, you need to be able to understand the data, and quickly. Visualization tools can simplify data, and make it easier to understand and spot key trends.

According to Deloitte’s “Tech Trends 2011: The Natural Convergence of Business and IT” report released in March, data-visualization tools were the fastest developing area in software last year.

Data in, graphic out: Visual representations of data are easier to understand.

Data in, graphic out: Visual representations of data are easier to understand.

“Data visualization compresses information quickly,” says S. Anand, 37, chief data scientist, Gramener, a Hyderabad-based data-visualization company. “For example, in a chart, a bar can give you a data set with its height, colour and thickness, so you have already compressed a table with three columns into one graph,” he explains. “A 40-page report can easily be converted into a single page of graphics.” By doing this, a large amount of data becomes easily accessible, and trends and highlights are easy to pick out, compared to a table of numbers.

“Data-visualization tools are typically designed to highlight relevant insights, rather than just present raw data as in a dashboard,” explains Stewart Langille, co-founder, Visual.ly, a new online visualization tool. Another useful aspect of viewing data as visuals is that you can highlight the information that’s really important and even get newer, completely unexpected insights into the data sets.

Like the idea? We list some of the most innovative online data-visualization tools:

Tableau Public

Website:www.tableausoftware.com/public

After you install the software, you enter the data either as a spreadsheet (Microsoft Excel, Microsoft Access) or text file with tab spaces. The software reads the file to identify variables. Once you choose the relevant variables, it creates a visual chart of your data. The software automatically tries to give the right kind of chart, but you can also manually choose from options such as bar charts, histograms, scatter plots, bubble charts, pie charts, bullet graphs, maps and heat matrix, etc. Tableau charts can also be interactive, so viewers can rearrange the data to analyse it from different perspectives. The chart is saved on www.tableausoftware.com

The downside is that visualizations and data are public—anyone can download your work. To keep it private, and for added features such as more filters and representations, you could buy the Personal Edition for $999 (around Rs. 50,300), or the Professional Edition for $1,999.

Cost: Free to use, with paid editions starting at $999.

Many Eyes

Website:www-958.ibm.com

Many Eyes, launched in January 2007, is one of the first data-visualization tools, and was created by IBM Research.

I blog for internet

Internet is a life-savior for me. I cannot imagine not checking out my emails, blogs and videos that have refreshingly non-censored language and sometimes when I have time (and inclination), even porn. So I write to support the Black Out Day today. I write to support the action against a supposed ‘democracy’ trying to stuff of the biggest democracy in the world – the INTERNET! Stand together people, because we have to do this soon in our country as well if Kapil Sibal has his way. Here’s something to keep you smiling in grim times. I am embedding more because soon I might not be able to do it at all.

 

 

Protest against what’s happening in USA now by visiting www.internetcensorship.org and signing a petition meant to come from international users.

 

PS: Is that how activists happen? You are just sitting around doing your things and then something comes along that doesn’t let you do them. So you have no choice but to protest against it, no?

Word Breakup: Poppy Shame and Eve teasing

I have been toying with the idea of doing a blog on the phrase ‘Shame, shame Poppy shame’ something that is used quite freely around me, though no one knows where and how it originated. I heard it recently spoken by my mother, who rarely uses English words when in family, use this phrase for my 2-year-old nephew when he was happily running around in the buff. The term is usually used for 2-5 year olds and sung in a nursery rhyme format.

The complete rhyme is: Shame Shame Poppy (or Puppy) shame, all the donkey’s know your name.

I have rarely heard the latter, just the first four words. The phrase is a part of a list of ‘If you Grew up in India is the 90s’ you use this phrase.

According to  samosapedia it is “a light hearted remonstration for some, usually minor, social transgression or faux pas, a taboo flouted, a line of decency crossed…”

I am not completely sure about this definition. It’s more than light-hearted remonstration for one. The rhyme itself seems to have come from the British rule, but the Indians have associated it more with the idea of nakedness.

The phrase is happily used in Pakistan as well as shown by this blog by an American woman married to a Pakistani guy. She mentions how her in-laws say ‘Shame, shame’ everytime they see her child naked. It’s the same as Indian households.

Author Salman Rushdie uses this phrase in Shame based in Pakistan where he talks about the idea of ‘sharam’ which includes an element of society with the English word shame.  It has been interpreted as showcasing an example of an hangover of the idea of shame in post-colonial discourses.

So I have a feeling that the phrase is not as ‘light-hearted’ but rather associated with our culture’s idea of nakedness as being something shameful and which should be hidden. Of course it comes disguised in a sing-song, smiling sort of a way.

Since I am obsessed with graphs in recent weeks, I searched for the word ‘shame’ in Google Trends  which tracks the ‘average traffic of shame from India in all years’. I was surprised!

 

 

 

What’s so shameful about 2007 and 2011 that Indians used or searched for this word so much?? Makes one’s mind wonder. Check out the whole analysis of the word here which will also give you region wise search, etc.

Hiding deep-rooted hang-ups about sexuality and ‘sharam’ behind sing-song phrases reminds me of yet another phrase for today:

 

Eve teasing

The word which has become popular to casually talk about the pinching, winking, breast-staring that happens in this country, has its own Wikipedia page. Quoting the rather nicely done definition there:

“Considered a problem related to delinquency in youth,[3] it is a form of sexual aggression that ranges in severity from sexually suggestive remarks, brushing in public places and catcalls to outright groping.[4][5][6] Sometimes it is referred to with a coy suggestion of innocent fun, making it appear innocuous with no resulting liability on the part of the perpetrator.[7] Many feminists and volunteer organizations have suggested that the expression be replaced by a more appropriate term. According to them, considering the semantic roots of the term in Indian English, Eve teasing refers to the temptress nature of Eve, placing responsibility on the woman as a tease.[8][9]

Apparently the word is very strong in Bangladesh as well if Google trends (I am obsessed!) has anything to go by.

“Eve teasing is a euphemism used in Bangladesh, India and Pakistan for public sexual harassment, street harassment or molestation of women by men.” – thedailystar.net

 

In India-only search, the phrase seems to have gained popularity in middle 2011 when there was a protest against the very idea.

 

The phrase seems to have its origins in India in the 1960s. I found a very interesting citation of 1960s on the website Double Tongued.

1960 Times (London, England) (Apr. 22) “Protection For Indian Girl Students” (in Delhi, India) p. 9: One aspect of the problem of student indiscipline which is plaguing university authorities in India has been the bullying and harassment of girl students in the few coeducational institutions—a pastime so common that it has been given the name of “Eve-teasing.”…“Eve-teasing” is not, apparently, just the oafish high spirits or ill-will of a handful of male students but is rather a symptom of the strong resentment which many students feel against women in the universities.

1963 Selig S. Harrison Washington Post, Times Herald (D.C.) (Oct. 26) “The Sad State Of India’s Youth” p. A8: Police officials have been discovering that the collegiate enthusiasts who prowl streets in Indian cities are not content to watch the girls go by. Indian newspapers have carried accounts of police roundups in Srinagar, Dehra Dun and other centers for indecent advances at bus stands and traffic intersections.…Happy headline writers have dubbed the new offense “Eve-teasing.”

The quotes above are from international media. I couldn’t find references to the same in 1960s Indian media. It had to be a journalist to coin a catchy, casual phrase. I place my bets on it being a male journalist. The phrase emerges from the authorities/media/patriarchal society talking jokingly about male students jeering at their fellow female students.

Eve and Tease are two words created by a patriarchal society which has been in the habit of leading and objectifying their women. It’s the same society which feels that the woman’s body is impure, full of things they don’t understand and so women are not allowed in temples during periods. Their bodies are objects which when covered should be venerated and when uncovered is a source of shame. 

The phrase manages to have a relaxed attitude about things like rape and at the same time squarely puts the blame for teasing/distracting serious, studious university boys on their fellow female students. It also places the blame squarely on women for having the tempting bodies and temperaments (again patriarchal perspective). The problem which Indian women are facing even today with a Karnataka minister blaming women for being raped because they wear tight jeans.  

It’s interesting to see how new words take on the same old meanings. Only more insidious.

I would like to close this with a link to one of my favourite blogs, http://blog.blanknoise.org/. Read it, if you are any gender, to understand what the other side, the non-patriarchal, the women, feel about the word.

Clothes and rape

The policeman said, don’t blame us if women get raped if they are dressed provocatively. Karnataka Women and Child Welfare Minister C C Patil said women should know how to dress or presumably face the consequences.

And here’s what the media said. I have used about 20 articles generated in the media (in English press) to see the words we use when faced with such a blatantly provocative statement from those in authority. 

 

women war

 

Interesting. I wonder if these words alone express even an iota of the rage I feel inside me.

My toothbrush travels

 

2011-12-Toothbrush-@maf1967

 

My toothbrush,

It travels

 

When no one has their eyes open

Or are listlessly staring

At the slow moving

Ceiling fan.

 

When all are lost

In their own private

Heavens or sometimes hells.

 

That is when my toothbrush

Slings its bag

On its bristly shoulder

And sneaks away

Mutedly

Into the dark lanes

Of unknown names.

 

It never speaks of it

Where it went

Or what it did.

It never lies too,

It just smells.

 

Of beds slept in by strangers

And roses dipped in honey

Sweat dripping from armpits

Or a nose that is runny.

 

That is how I know.

That it sometimes goes

For when we touch

And make love

When its bristles tickle my teeth

Sometimes I smell

The dampness of the beach.

Muses are like opportunities

Muses are like opportunities. They come knocking on your door at unexpected times. Sometimes you have been waiting impatiently, looking at your cellphone screen’s right hand side corner for that precise moment to strike, tapping your fingers on the side board. At times like those, you open the door without waiting or wondering who it might be in the middle of the night.

Sometimes you go out looking for muses, your hair spread wide, like a cuckoo’s nest (BTW, has anyone wondered why cuckoos keep their nests so haphazard? Maybe it’s avant garde style yet to be recognised as such). You ask stray cats, sleepy dogs and curious ravens if they have seen any muses (or opportunities can also do, please). They all shrug, look back at you like you have lost a bolt or two.

Then there are times when muses fall into your email box. There they lie, along with emails from the banks you don’t have accounts with, enthusiastic group emails of astronomy you don’t remember subscribing to and emails from sellers who are convinced you cannot do without such-and-such baby oil or book. But even when the said muses have been served to you in a platter (or in this case, your inbox), there are chances you might miss them.

You might just delete that email without opening, like you have done to other emails from this website you had subscribed to long back ago, but don’t remember why. You might open it, with cynical curiosity, scanning the email because you don’t want to go back to that synopsis you have to prepare. Even if you open it, you might fail to click the link of a short translated story of a Spanish author whose name you cannot pronounce. After all, writers and writings are out there on the internet paisa a pandrah. Then you might open the link but forget to read it as it lies waiting amongst the other tabs opened for later reads.

So that’s why if you do end up reading that story at all and realise with surprise that it was at all this time a muse, waiting to spring up and surprise you, to fire your rockers into writing,  like a virus hidden in an attachment, it’s nothing short of a miracle. The muse is an unexpected best friend that landed at your doorstep, just when you were standing in the balcony, wondering what it will feel like to jump. 

All this while, all you had to do is click one email link. A simple click which would have saved you from those empty days when you look in the space and no thought welcomes you. Just a simple click. Was it meant to be? Is this how destiny works? Or is it just a web, an intricate spider web of unexpected choices you constantly make every moment of your existence? Is it free will or do you have no choice in the matter? How can you ever be sure of either?

All you can do is bow to it. Smile, thank the skies, or if you believe in chaos, thank chaos. Write a blog, write a poem and scribble down the thoughts that strike you for your novel. After all, you have been granted the gift of a muse today. It doesn’t happen every day.

This post is dedicated to a muse who came unexpectedly and resulted in this blog. Thank you Juan Villoro and Word Without Borders for the unexpected muse called Holding Pattern

Time to pitch is now!

 

Finally the day has come. And what can be better than the start of the new year to do something that you have cringed from all of last year? I am going to close Mystery of the Iyer Bungalow (yes, dear readers, it’s still not published. The reason is that it’s still being edited and has not been even shown to a publisher yet). I have begun the process of pitching its manuscript to publishers starting January. I was afraid all of end of last months of 2011. I cringed, stalled, questioned, panicked, and analysed. Basically did everything in the WHAT IFS category and didn’t pitch the book.

Now I am geared myself for rejections, criticisms, rotten tomatoes and jeers. Basically anything and everything that anyone who wants to throw can throw at me.

Maybe it’s the new year. But I am determined. I am determined that I will follow my dream and write and write some more.

 

MY NEW YEAR NO-RESOLUTIONS

Here are things I am NOT going to do this new year:

  • I will not be afraid of reactions to my writing.
  • I will not think on writing and not write.
  • I will not compare.
  • I will not worry about what my life would have been with different choices
  • I will not be afraid out trying new things.
  • I will not worry about how bad I write
  • I will not equate success with the money I could have been earning.
  • I will not feel lonely and boring.
  • I will not feel envious of books I enjoy reading.
  • I will not stick to my comfort zone.

With so many things I had been doing, it’s a wonder I still write. Stubborn I think :)

 

A sentimental note for Mystery of the Iyer bungalow: As I put in the finishing touches to the my first manuscript of the Mystery of the Iyer Bungalow, I feel a sense of anti-climax. While editing the book, I realised that it could have become so many other books with the same characters, with the same settings.  I would like to change it a bit, tweak it from here, add things to that side, but I cannot. Not anymore. I know it’s not perfect still, I don’t think it ever will become perfect. Like a mother, I feel I am over-fretting on my child rather than setting it free. So many emotions. When did I become so attached to just words? I hope someone else becomes attached to this imperfect book, reads it and enjoys it. That’s after all, the most important thing.

Plug in, and tune out everything else

 

Looking for headphones? Don’t make do with the free pair you get with your gadgets. Get a pair that suits your needs

 

Earphones are being used with every gadget today: a tablet, a smartphone, an MP3 player or even a wireless set with the TV if it is in a bedroom. “Most of us don’t hesitate to invest in a good gadget, but forget about the earphones,” says Bangalore-based Sridhar Reddy, 38, an audiophile and independent consultant on custom-made audio systems.

“The earphones that come as a package deal with most gadgets are basic. They don’t fit our ears well and if they do, they don’t do a good job of blocking out external noise,” says Reddy.

These generic earphones also fail to adapt to your lifestyle needs—answering calls on the go or running while listening to music. “A good pair of headphones is necessary to enjoy your gadget to its full capacity. Serious audiophiles, for example, will never go for in-the-ear earphones. They like them big and round so that music can breathe,” explains Reddy. In the same way, if you answer a lot of calls while on the move, the last thing you want is static in your Bluetooth headset. We list headphones to match your every need.

• Music on the move

Want headphones that stay with you and give you good quality music while you run, sweat and work out in the gym? The Sennheiser Sports series has three different designs, PMX 680i, OMX 680i and MX 680i, for medium-to-heavy workouts. They are highly flexible, so you can run faster or work out harder without worrying about dislodging the headphones. All of them come with a powerful stereo sound, an integrated remote, built-in volume control and a microphone to track and take calls in the middle of a workout. The kit includes many accessories and sleeves, to make sure you find the perfect fit for your ears and the earplugs stay firmly in place. The earphones are sweat- and water-resistant.

Money Matters: Rs. 3,990 for PMX 680i and OMX 680i and Rs. 3,290 for MX 680i, available at select stores. Check for discounted prices on www.gadgets.in

TV watching

Don’t want to disturb your partner with your idiot-box viewing? Help is at hand with Sennheiser RS120 Wireless Headphones, which come with a charge station. Though they are older than the more recently launched Sennheiser RS180, they are still our favourites for the amount of listen-time they give in one charge (20 hours, rather than 6 hours in the newer model), so you can use them for longer without having to get up and charge them. These wireless headphones have a range of up to 100m, come with volume control, and give a detailed sound reproduction with strong stereo bass. The reception works through walls and ceilings. They are lightweight and very comfortable to wear.

Money Matters: Rs. 6,190, available on www.letsbuy.com

• Cut off sound

Your work requires you to make transcripts from audio recordings or your office is just too noisy and you need music to help you concentrate. Or perhaps you want to listen to music while on your way to work, but the noise from the road makes it impossible to enjoy yourself. Noise-cancelling headsets help here and the Bose QuietComfort 15 is the best option. Each headphone earcup comes with an inbuilt microphone both inside and outside. The microphone senses and cancels the sounds that are filtering in from outside, keeping your ears noise-free. You can use its microphone for a hands-free phone conversation too, though that works only with an iPhone. An average AAA battery makes the headphones last about 35 hours. The QuietComfort 15 is comfortable, with ear cushions, lightweight and collapsible, and can be packed compactly in case you want to use them while you travel.

Money Matters: Rs. 17,550, available on www.boseindia.com

Also try:Sony MDR-NC200D Digital Noise-Cancelling Headphones, $179.99 (around Rs. 9,750), plus shipping, available on www.ebay.com. Its noise-cancelling technology drains battery faster but the headset is quite good at blocking external noise. It is also lightweight, cushioned, and can be folded compactly.

• Pure audio

If all you want to do is listen to music as if it was being performed right in front of you, opt for Audeze LCD-2, manufactured by the Las Vegas-based niche company Audeze. The headset prioritizes quality over portability or affordability. The technology used is rather different from most headphones—each pair comes with tiny dynamic drivers that are mini versions of the drivers used in box speakers. The Audeze uses thin-film planar magnetic drivers and larger diaphragms that project sounds around your ear rather than straight into it, creating more depth in the notes. The thick lambskin earpads sit softly on your ears and are comfortable to wear for long hours.

Money Matters: On special order for $995, with $115.58 in shipping, available on www.audeze.com

Also try: The Audio Technica ATH-M50 for Rs. 13,913, available onwww.ebay.in, offers performance on a budget. Meant for professional studio monitoring and mixing, its over-the-ear cups create a seal for maximum isolation
