Amid the mask mandates and choropleth hospitalization maps, we settled into something we’d never had: a life together.

A choropleth map of the area might show that there was a cluster of cholera cases, but it might not, depending on where the boundaries are drawn.

They created a choropleth map of the results, using a location quotient whereby shading indicates the volume of followers relative to the total number of Twitter users in a given country.

It’s a good counterpoint to the usual choropleth political-affiliation map in which little islands of Democrats float among a sea of low-density Republicans.
