"Thematic Mapping Engine (TME) enables you to visualise global statistics on Google Earth. The primary data source is UNdata.
The engine returns a KMZ file that you can open in Google Earth or download to your computer.
So far only prism maps are supported, but other thematic mapping techniques will be added in the upcoming weeks."

Fascinating "stuff" that's easy to do, and sure to start some great discussions on these important issues.
