Maps and visualizations

I found this at HN a couple weeks ago

Apparently most of these come from a reddit  http://www.reddit.com/r/MapPorn/ . Some of the maps can be good topics for dinner discussions.. its a definitely intriguing list.

On the visualization topic, I really want to find a reason to play with D3.js ....
