Some Visualizations I Like
and Had Absolutely Nothing To Do With

Here's a map of Africa. The visual impact is immediate and needs no explanation. The image is in the Creative Commons, so I have it here in a somewhat expanded version. The map on the artist's site is here.

This is storm surge inundation from NOAA. It shows the entire east coast of the United States. Even a legislator should be able to understand it.
