Number of U.S. Congressional Representatives by State, Over Time

Instructions

Try using the "Select a state" menu, and hovering and clicking on the small squares.

If the squares are too small, zoom in.
(control+ or command+ on most browsers)

This seems to be working in current desktop versions of Chrome, Firefox, and Safari,
but not in IE or Opera. I haven't tested on older browsers, nor on iOS or Android,
although it seems to mostly work in Chrome for Android.
