contributions to scott walker’s wisconsin recall campaign. circles sized by amount donated (per address). first photo is on a light background, which serves to eliminate noise and focus on point density/clustering. the dark version makes it easier to see regions where contributions aren’t concentrated. the next two photos use rounded latitude and longitude points to get a cleaner picture, with the first overlaying all points on top of each other, and the the next showing aggregated amounts for each rounded lat/long pair. (data from http://data.influenceexplorer.com/bulk/)
prisons, correctional facilities, and jails in america. circle radius determined by (absolute) facility population (max=9796). added a second dimension of color because overlapping circles and semi-transparency obfuscated the true prison sizes and made it difficult to see patterns.
