I am always on the lookout for new and interesting visual representations of complex data and just discovered Death & Taxes, 2009: “is a representational poster of the federal discretionary budget; the amount of money that is spent at the discretion of your elected representatives in Congress. Basically, your federal income taxes. The data is from the President’s budget request for 2009. It will be debated, amended, and approved by Congress by October 1st to begin the fiscal year.” You can buy the poster but also access it through a somewhat clunky flash interface.
