Cartograms are usually pretty mundane, but throw in Flickr, Photoshop, and a well-known public place and you have an artistic representation of popular colors. Much more eye-grabbing than your common map.
The colors represent what people on the ground are looking at in the specific physical-cultural landscape. Based off the most recent 2,000 Flickr geotagged photos, Cartogrammar found the average color in each photo, plotted it on the map, and interpolated them into a vivid diagrammatic rendering of our most favorite colors in that area.
The following photos show the process of color coding Boston Common:
