Just in time for tax day here in the U.S., Google's Data Viz Challenge, a five-week developer competition, ended and the Grand Prize winner announced. The winning entry is called simply "Where Did My Tax Dollars Go?" and was created by Anil Kandangath. The Google-sponsored contest asked developers to use data visualization techniques to demonstrate how our federal income tax dollars are being spent. Over 40 developers submitted entries that offered everything from pie charts to bar graphs and more in order to make this complex data more accessible and understandable by everyday taxpayers.

Curious to see how your tax dollars are spent? Check out the winning visualization below.
