The above link will take you to something called a squarified tree map. It is of the Presidents proposed budget. I love squarified tree maps. We have been using them at work to condense and display huge amounts of long-term data. As it is used in the link, it is a very nice way to show how much money would get spent and where.
It’s probably time to start hacking away at National Defense, Social Security and Medicare. Or maybe we should cut spending on Natural Resources, since it comprises a whopping 1/16th of the budget, and because clean air and water aren't really needed, nor wilderness, fish, wildlife, birds, etc...-Sarcasm.
