Weekly Map 8

#8: Last week's task was to find an interactive Javascript map -- any topic. Think along the lines of Labs 9 and 10.

This interactive map isn't one that I particularly like.  It gives too much freedom to the user, letting them decide the classification system, color palette, and the data displayed.  I feel like it's not so much showing the user something as offering to show them everything, and as a result there are a lot of ugly map possibilities.
