Animated Cartogram showing 2012 Presidential Election Results

Animated Cartogram

The size of geometries does not tell everything. Cartogram is a cartographic technique or product that transforms geometry to show statistics like population or electoral votes in presidential elections. I have published a few algorithms that can produce topology-preserving areal cartograms. This web visualization is a demo of various methods to show statistics using transformed geometry as well as color and alpha (opacity or transparency).

The web visualization is built using d3.js and simple bootstrap, with its core library and the geo, projection, queue, transition, and topojson modules. It utilizes vector polygons (representing states) with animation driven by smooth transition.
