amazing. great demonstration of when graphical representations let us understand information in a clearer way. of course, i’d like to see some other maps as well - population density, racial distribution, etc, to get a clearer view of the correlation, but it’s still quite interesting. (pin the tail, big ups to dave for the link.)
