This is a representation of historical outlays by the federal government that allows you to compare and contrast any two years from 1963 - 2014 and to see which items have changed the most from year to year. All budgets after 2009 are projected. All amounts are in 2008 dollars and per capita for any given year.
This Thinkmap application uses a combination of the Hierarchy display with the ability to scale nodes based on any property. By default, the names of budget items that are smaller do not appear, unless a user rolls over the node. A user can also find specific items through typing in the search box, or through adjusting the percent increase filter.
