Left-click in view, then use your arrow keys to move around in 3D space (with control-key for up and down).
Hit the 'f' key to reset to front view, 'b' for back, 'l' for left, 'r' for right. Click on a representative to zoom.
Move your mouse cursor over a rep to see their details .
In the front view, the reps towards the left are Democrats; the reps towards the right are Republicans.
The representatives' locations in 3D space are determined by their votes in the 111th Congress as reported by http://www.govtrack.us/. A total of 1655 votes were cast, though not every representative cast every vote. Represenatives appear close together in the space if they voted the same on many bills. Representatives who voted differently on many bills appear further apart. It's self-organizing. The points were generated from the raw data by a technique called multi-dimensional scaling via relaxation.
