Cartographic animations involve the aspects of cartograms with the use of different elements, such as lines and dots to represent data. The difference from regular cartograms is the use of animation. The cartogram above features population of London. The map features animation in which with each year change, the map's colors change in reference to the migration of the population from 2001-2031.
