Some useless   data visualizations and infographics

Here you can find a collection of info graphics and data visualization on various topic. Most of them are based on data , basically related to programming languages which are tags in questions asked. All data for stackoverflow is collected using Stack API. These are experiments with javascript data visualization library D3.js. Most of these data can be visualized with a bar or pie chart, but here I am choosing different types of data presentation just for the sake of it.
