Google Charts API - Maps New!
The Google Chart API lets you dynamically generate charts on the fly.

Google Chart API now generates thematic Maps.
From the Google Chart API Group:
"We released a new version of the Google Chart API. It adds many new features that you requested here in this group, for example sparklines, radar charts and thematic maps.
The most important change however is that we removed the limit on the number of requests. This means you can use the Google Chart API without worrying about reaching a limit.

The example Chart API Map (above) can be generated with this url.
http://chart.apis.google.com/chart?cht=t&chs=440x220&chd=s:_&chtm=europe&chld=GB&chco=ffffff,edf0d4,13390a%20=GBFR&chd=s:Af9&chf=bg,s,EAF7FE
This would be good if you could overlay kml...
or overlay pie charts (or any other) onto a Google Map.
