As I predicted, now you can display population density data in Google Earth, thanks to the work of Imran Haque, a grad student at Stanford (boo!) though he was an undergrad at Cal (yay!). His program, gCensus, allows the drawing of polygons over Google Maps, which the Google Map API doesn’t do well on its own. Combine that with freely available US Census data and genius happens. Do I get any credit for predicting its development? No? Ok.
