The choice of a red-green gradient is probably not wise, considering the prominence of people with red-green colorblindness. ( Screenshot http://bit.ly/fcRHRk http://bit.ly/fcRHRk vs filtered screenshot http://bit.ly/frqlxP http://bit.ly/frqlxP — Note the similarity of NYC and Jacksonville.) Otherwise, I really dig the execution of the map. EDIT: Cached the filtered screenshot so as to not hit the (relatively slow) colorfilter.wickline.org server.
