Visualization of the Day: The Population Growth of 590 Cities
This chart might break your brain.
Warning: This chart might break your brain.
Barcelona design concern Bestiario has compiled the population growth data for 590 cities and crammed it all into one intensely jazzy visualization. The timeline begins on the left side in 1950 and is projected forward until 2025, with each column representing a five-year period. (The data comes from mapmaker Nordpil.) You can highlight a city's growth by clicking on its color-coded line. They are stacked in order of population size, with Tokyo on top and... I don't know what's at the bottom, as my mouse can't click that precisely. Łódź, maybe?
