Drought extent by region

For Scientific American, Cédric Scherer and Georgios Karamanis charted drought extent by region using a grid of stacked bar charts. Each cell represents a year for a corresponding region, and color represents drought intensity.

Compare this view to more map-centric ones. This version focuses more on time than it does geography. One isn’t better than the other. Just different.
