Google’s Data Viz Challenge is rewarding designers with $10,000 to create some next level data visualizations revolving around the way US federal income taxes are spent. All data is coming from WhatWePayFor.com, and your entry must be graphical and have a relationship with underlying data. Judges include data viz masters Aaron Koblin and Jonathan Jarvis, both visual big wigs. Unfortunately the competition is for people based in the US. If that’s you, get on it here.
