Facebook Ownership

Another interesting piece of data that I stumbled upon is on the ownership on Facebook on http://www.businessinsider.com/chart-of-the-day-facebook-ownership-2011-12 .

I find that not only that there is a small error in the data, but the use of pie chart spoils its purpose.

Here is the image.


Now here are the confusions in this Viz.,
  • Use of colors are inappropriate. The smaller sectors are hard to differentiate leading to loss of understanding of data.
  • Hard to compare between who is larger owner just by seeing the pie chart.
  • Colors in the legend is hard to see and correlate with the chart.
  • The sectors also do not provide enough data via proportion for analysis.
Now apart from all this, there is a small error in the data. We see that both Goldman Sachs' Clients and Perter Thiel/Clarium Capital are accounted for $3 billion , but the quantifiable percentages being 3% and 4% respectively. This might have arose because of approximating to the nearest number, but should have done appropriately.

What I would have done differently is plot this on a simple bar chart, like I tried here. [Click on it for a larger view]


You can see that the data appears in a more clear format now. There error in data still persists though, since my whole intention was to provide a better visualization. 

Here in this chart we can clearly see who owns what percentage of the company and how much amount is involved. We can also correspond the details along with the owners name, unlike in a pie chart where we have to map each sector and color to the name.

For the accurate data on the ownership of Facebook, please visit http://whoownsfacebook.com/

I have used Tableau software to create this visualization, it can be downloaded from http://www.tableausoftware.com/ .

A change in perspective

I came across this post on http://visual.ly/areas-europe , which actually communicates a rather simple piece of information - Areas of all the European Countries. It got me thinking as to how far could someone go to complicate anything.

The Viz., which was posted on the website is
Source : http://visual.ly/areas-europe
Phew!! that's tough to decipher. What this visualizes and is trying to communicate is basic information as I mentioned above - Areas of all the countries in Europe. Though we see that it has some artistic effect to it, it becomes tough trying to understand what it is trying to tell us. This is a basic bubble chart, where the size of the bubble corresponds to the area, positioned alphabetically. However we see that Europe is positioned last which can be ambiguous to a few.
The ambiguities that we can see here are:
  • Which bubble corresponds to which country - Due to fair amount of overlaps
  • Europe placed at the last - Is this considered a country too, if so where is its bubble, if not why is it there?
I gave a shot on trying to make it simpler. You can click on them to make them larger and have a clearer look.


This is a very fair simple example (less artistic though) which clearly depicts the areas of each country belonging to Europe. This is a simple bar chart where the length of the bars shows the areas, lined in a descending order of their respective areas.

What is clear in this viz.,
  • Country names
  • Areas of each country
  • Comparison
Another try at making this better is.,


Here I have ranked each country based on their areas largest being ranked 1 lowest being 49. The shade in the color shows the difference in ranks.
I wish I could embed the Viz., here so that the area details could also be shown, if I had done that here, it would be cluttered.

The tool I used to make these visualizations is Tableau, which is available for download at http://www.tableausoftware.com/

Wolfram Alpha ( something interesting )

Hey friends....

This time i would like to show you something interesting on the internet. (move to the last after noting the link in this article if u r bored )
This is related to a person whose credentials are something unending.


Stephen Wolfram (born 29 August 1959) is a British physicist, software developer, mathematician, author and businessman, known for his work in theoretical particle physics, cosmology, cellular automata, computational complexity theory, computer algebra and the Wolfram Alpha computational knowledge engine.

Wolfram Alpha (styled Wolfram|Alpha) is an answer engine developed by Wolfram Research. It is an online service that answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer as a search engine would. It was announced in March 2009 by Stephen Wolfram, and was released to the public on May 15, 2009.It was voted the greatest computer innovation of 2009 by Popular Science.

You can reach it at www.wolframalpha.com

The following are a few examples of queries you can use in Wolfram Alpha. They are accompanied by links to the results of each search to illustrate the variety of answers that Wolfram Alpha provides to non-specific queries.
• mortgage 6%, 25 year, $140000 displays, among other things, repayment rates and graphs that represent capital vs. interest over time.
• life expectancy france 25 year old male which gives a survival analysis for a person of the given demographic.
• boiling point of water at 6 atm which returns a phase diagram alongside the result of 432.6 Kelvins.
• lim(x->0) x/sin x yields the expected result, 1, a plot, and the series expansion. The button "show steps" provides a possible derivation of the result using L'Hôpital's rule.
Wolfram Alpha is also capable of responding to increasingly complex, natural-language fact-based questions such as:
• "Where was Mary Robinson born?"
• "How old was Queen Elizabeth II in 1974?"
• "What is the forty-eighth smallest country by GDP per capita?" yields Senegal, $1090 per year.
• "What is the speed of a swallow?" yields the assumption, "Assuming estimated average cruising airspeed of an unladen African swallow", and the result, "there is unfortunately insufficient data to estimate the velocity of an African swallow (even if you specified which of the 47 species of swallow found in Africa you meant)." This is a reference to a joke from the movie Monty Python and the Holy Grail.
• When asked "What is the meaning of life?", it replies 42. This is a reference to The Hitchhiker's Guide to the Galaxy novel, in which a supercomputer is told to calculate the meaning of life, and it finds the answer to be 42. These and all other "humorous" queries are individually written by programmers and not "understood" by the software on a deeper cognitive level.

Also, one can input the name of a website, and it will return relevant information about the site, including its location, site rank, number of visitors and more.

The database currently includes hundreds of datasets, including current and historical weather, drug data, star charts, currency conversion, and many others. The datasets have been accumulated over approximately two years, and are expected to continue to grow. The range of questions that can be answered is also expected to grow with the expansion of the datasets.
Wolfram Alpha is written in about five million lines of Mathematica (using webMathematica and gridMathematica) code and runs on 10,000 CPUs (though the number was upgraded for the launch).

As well as being a web site, Wolfram Alpha provides an API that delivers computational answers to other applications.

Well then enjoy working on it. Most interesting thing i found out was typing in the names of two companies or two countries and seeing the results....do try it. ( You can also type in your name n see something interesting )

Social Problems Faced by Youth....

We see a lot of change in our surroundings today. We also have witnessed constant change in the economy of the world, how it has been affecting organizations and people alike. Moreover the cultural changes that is spread in India and also in the rest of the world has been worrying.

The changes in the social surroundings include natural changes, cultural changes, economic changes, status changes and many more. The ups and downs, high and lows in each of these affect the social man. One of the reasons being, man has been an imitator from the time of his birth. He has been aping all that he finds around himself. From the time of birth, the language he learns, the mannerisms, his character and his culture all are imitations of what he sees around. So his own behavior is subjected to change according to the social surroundings he is in.

The changes in the factors that affect a man’s behavior may be temporary or permanent. This depends on the amount of time he is exposed to the change, the severity, and his own determination and will.

The problems we may talk of in a society due to various changes we find may not be a problem to many others. It depends on one’s own perceptions and perspectives. It may also change from one generation to another. What may be termed as a problem to one generation may not be to the other, or we may say that, the generations to come may evolve with them. The generation we live in too, has learnt to live with many situations and changes which were termed as problems by our ancestors.

The same is with what we term as ethical. A peace loving nation says bringing peace to the world is ethical, whereas a war minded society may say otherwise.

It is left to the individual to deicide what is ethical to him and what is a problem to him. As per Gandhi the father of our nation, for a nation to improve the society should, for a society to improve the individual should. Many legendaries have stressed upon the betterment of an individual first then on societies then the nation. The reason being, individuals make a society and societies make a nation.

The youth of today are the pillars of tomorrow. Quoted in another way, the youth of today are the pillars of the nation. For a better and prospering nation the youth has to be the best and prospering. They need to be given the best of knowledge and wisdom so that they may decide wisely between the right and wrong, wants and desire, need and surplus.

There are a few problems which needs professional help and some which can be curbed by individual initiative. We need to understand them and offer our support to people and help solve such problems. A proper knowledge of these should also be given to the upcoming youth.

As the youth of the nation it is our responsibility to know and take right action against the problems we face in our own society. We also have the need to know how to react to the various happenings in our society. Being ignorant or not reactive to the happenings around us helps no one. But we need to be knowledgeable and supportive to curb the wrong doings in our society which may affect us and the future in a wrong way.

Terrorism is a word all of us a very familiar with today. It now has become a word which we hear on a daily basis. We have heard and seen in many occasions that kids below age of ten also handle guns in a few parts of Africa. Also most of them are very well educated too. We hear from the news that terrorist who were caught are graduates or degree holders in arts or science. Also they are being paid handsomely. Such is the reach of terrorism in today’s world. It is mostly youth who enter and join them. One among many ways to stop this is to counsel the youth, don’t allow them to be brainwashed by wrong people. The people who come to brainwash them may have many excuses for what they do, but we have to decide what is right according to us. Is killing innocent people in the name of religion or country right or is having talks of peace and negotiations without bloodshed the way to peace. Remember war never brings peace.

Crime is another issue the youth of today face as a problem. When we open the news paper we find the crime pages thicker than any other page in paper. Murder for few amounts of money, revenge, rape, robbery, cheating etc are what we read early in the morning. These have become so common that we just read and forget it. They may not even be a matter of discussion or concern in our lives. A perfect example of how non reactive man has become today. As responsible citizens we can lend a hand in this by securing ourselves and not giving a chance to anti social elements to harm us. Prevention is better than cure is something we hear and tend to follow, prevent yourself from being harmed, and be alert, cautious and conscious.

Calling politics as an issue may not be right. But today if I call it a root for many issues we witness in our cities I may not be wrong. Bandh, strike, hartal, bring about a smile in the faces of kids and youth as schools n colleges remain closed, so do the elders feel good as their offices remain closed. But the amount of loss the government undergoes in ways of transport and trade is huge. Public property is made from our own hard earned money, spoiling and breaking it means spoiling and breaking our own property. Understand what we do and think and act accordingly. Joining such anti social elements in such activities does only harm than good to us.

Lack of roots is one other big problem. By this I mean lack of proper communication with relatives, loosing touch with them. This is pretty natural when the individual gets busy with work and study, mostly due to off shore study and work. Many of us don’t know or even have lost contacts with our cousins. Things are alarming in the west, where brothers and sisters too have lost contacts with each other, or even with parents. The problem arises in such cases when the person is in some problem, he finds very few people to share or help him out of this. The more people you know the more relieving it would be in such cases. Though we may have friends people with whom we have blood relations and of the same cultural background may prove more helpful at times. We should be able to be in touch with most of our relatives; this can also serve as a stress buster at times where we could have a family get-together and plan various activities.
Being too social in life is a problem and so is not being social. Lack of communication within the surrounding areas of house is one other problem the youth faces. This too is something which comes as a result of busy lives. We don’t know who the person is next door. We don’t know the persons who live in our colony. They may prove useful at times necessary. When we live far from house and suppose a case of an emergency, we have our neighbors to come to our aid. The person staying next door may be a doctor, or police personnel who may be of great help to us. Knowing them and having a friend among them is of great use. This has been changing nowadays where people working in the same organization have been staying together in the same colony.

India is a land of diverse cultures. Each of them has its own uniqueness and beauty. Cultures and rituals of each region have its own grace. Everything has now become a compulsion or part of a bigger thing. Most of them are being omitted and skipped due to lack of time. All rituals performed, cultures followed have its own meaning and importance, and nothing can be exempted by terming it as waste of time. Many churches in the west have been closed down or are converted to marriage halls because people don’t go to church. Most rituals have a scientific explanation for their effects and many still being found out The Holy mass offered by Christians, the puja offered by the Hindus, namaz by the Muslims all the prayers are being offered to one God. People of one clan need not discriminate the other or people of the same clan have to understand the importance of their own rituals and cultures. We all need to learn to live in unity. The religious fights we see in various places in India all of no worth or meaning. The youth has to understand this and learn to make friends with all of them. Remember in India we follow “Unity in Diversity”.

Aping the west in many things is one other trend we see in our daily life. This is called the “in thing” today. This also poses a major threat to the culture of India. Not to mention the problems the youth face due to this, physically, mentally, psychologically. The youth are moving to live in relationships, platonic relationships, which may not pose any problem now, but surely in the near future. Pub cultures, night culture, one night stands, have become a common thing in many metropolitan cities and are fast catching up in other cities too. A realization lacks that the pleasures that are got from this are just temporary and may pose problems too. Peer pressure is one among the main reasons for more and more youth to fall into these. Counseling and guidance may help and stop youth from falling prey to them. Parents can also take a step in understanding the youth, their problems, talking to them, help them solve problems and various other measures.

The mental status of adolescents can never be predicted. They may be fine at one moment and moody at another. They scale and react to situations differently at different moments. Youths who are students may be held in peer pressure or parental pressure; this may do well to them or also be harm, according to the pressures they undergo. Many youths successfully overcome all this and shine in life, but some succumb to them. After their study life, another big question in front of them would be employment; people who get into jobs lead a peaceful life until they join and the rest go through lot of mental pressure, being answerable to self, parents and to many questioning mouths in and out of their family. The success and failure and each stage of their life moulds the individual in a special way. The youth has to take each phase of life with a special courage and be prepared to face any hurdles that come in the way. They should learn to take life as it comes but with a certain plan in mind and act accordingly. Celebrate success and gain experiences from failures. Thomas Edison Quotes “I have not failed. I've just found 10000 ways that won't work”. Believing in the thought that “All that happens, happens for good” and that “There is a time for every good to happen in life” may help many of us get over our failures and start afresh.

The busy life and schedule in our lives have caused many problems in life. Our perceptions also have played a villain. Small yet effective ways can help us cope with many problems in our life. Many practices likes yoga and reiki help us clear our minds and help us keep our calm, which in turn help us find solutions for many problems in our lives. Counseling youth on ways of life and parents on how to lend a hand to the youth in their decisions may be helpful. Youth also needs to take up a few responsibilities and learn to understand and adjust to a few things in the society. Having proper priorities in life help setting clear goals in life, this can help in finding time for everything and everyone. Wise decisions and calm mind is a perfect combination for a good character.
