Data visualization

In one of blog of Forbes India, blogger, NS Ramnath is talking about lateral hiring in big daddies of IT service industries. He collected data about and movement of laterals from Linkedin. In his this blog entry Ramnath has given a offer that if someone can come up with better infograpic, he will publish at his blog.

I thought of, let’s have a try. Before coming to actual infograapic, I noted down few ground rule:
1. Infograpic should be easy to understand
2. Infographic should have data arrangement in such a fashion that machine based analysis can be done on that information.

First I collected all available data present in the blog entry (purposefully not extracted more data from Linkedin or other sources) and compiled in tabular format.

To make data more presentable, I eliminated the datapoints which have gaps on data line, namely data pertaining to Accenture and Oracle. Also tried to extract some information from raw data and result is:


Now to depict the employee movement and gain/loss of company, I came up with following infograpic:

If you have any other idea, let’s publish it.
