Google today announced a Data Visualization Challenge that is well suited to the graphical capabilities of R. The goal is to visualize the US Federal budget from the point of view of the taxes an individual pays. The data are available from whatwepayfor.com — their FAQ gives details about the source of the data and the philosophy of making how our taxes are used more widely understood. If I can make a humble suggestion, I'd love to see a data visualization on how the tax burden has changed over the years — data are available back to 1985, which includes Reagan's second term — to help refute the misconception that present-day taxes are historically high.

Submissions are due by March 27 and are eligible for $10,000 in prizes, including $5,000 for the grand prizewinner.
