Where are all the rich, single guys in Manhattan? Why, the East Side and Chelsea, of course. We figured that out using GeoIQ's heatmap technology, which displays information using futuristic gradient shading. They've released two sample maps: a New York vs. San Francisco demographic comparison (rich, single men in SF seem to congregate near Union Square!) and a traffic map, which you can use to compare congestion in various cities. For instance, here's NYC vs. LA-- aren't you glad we have a working subway?


Via OgleEarth, a great maps blog. Thanks, Stefan!
