quickthang: cartograms

August 5, 2015

I thought this was cool, and maybe relevant to the presentation of demographic election data.

cartogram is a type of map, where you divide up a geographic area into regions which have numerical data associated with them (like what GIS is used for), but then you distort — stretch or shrink — the shape of the subdivisions to reflect one of the data dimensions, like population or GDP. You then use color as normal to show other data dimensions.
