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.
prisons, correctional facilities, and jails in america. circle radius determined by (absolute) facility population (max=9796). huge thanks to the creator of prisonmap, josh begley, for discussing his project with me and giving me tips on scraping the data from prisoners of the census.

i got ahold of some cabspotting data for a single day (jan 5, 2011) in san francisco, CA. these are some photos of me exploring the data— nothing new here. the photo with static-width lines is data for 20 cabs, the dotted photos are the raw cab GPS coordinates for 50 cabs, and the photo with varying-width lines is an attempt to track speed of the cabs between sequential coordinates. d3/polymaps, but i leaned heavy on polymaps for this one with a lot of emphasis on building valid geojson on the backend.
