The Data Viz Challenge was created by Google and Eyebeam to challenge developers across the country to visualize how are our tax dollars are spent. We received dozens of unique, creative submissions that help make our taxes easier to understand and, hopefully, less boring. That's the power of data visualization.
The data was provided by WhatWePayFor.com. The submission period ran from February 22 to March 27, 2011 and the winner was announced on Tax Day (April 18, 2011).
