The White House uses the JavaScript InfoVis Toolkit

I was surprised when I entered the main White House website the other day to find out that this logo was showing a very familiar treemap.

Clicking on the logo took me to another page where this treemap was featured. The application / visualization showing the 2012 budget is made with a TreeMap, in JavaScript, using the JavaScript InfoVis Toolkit. Click on this link to go to the White House page that features the visualization.
