It's that time of year again. Obama recently released his 2012 budget proposal for how to allocate $3.7 trillion. It's complicated no doubt, but Shan Carter and Amanda Cox of the New York Times make it easier to understand with their interactive treemap. Rectangles are sized by proposed spending and colors indicate percent change from previous year. Darker red rectangles represent bigger drops from the 2011 budget and darker green greater increases. Zoom in and pan as you please.
