this one is for my fellow map nerds. i’ve been hacking on a svg-to-map-tile script, and i got polymaps to display some of the tiles it created from a svg viz! if you’re interested in mapping and what goes on under the hood, please check out the script and shoot me some feedback.
cabspotting data. prints coming soon.
terrorism, 1970-present. redux. circles sized by number of fatalities. top is new colors, bottom is original colors. in both, lat/longs are rounded. check out the high resolution versions for more detail: new colors high res, original colors high res
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.
