In honor of Juneteenth – and as my (very small) part of an effort to ensure that we in the U.S. never forget our complicity in what was an abominable and evil institution – I present this choropleth map of slaves in the United States in 1860.
Adolph von Steinwehr was a German military officer who emigrated to the U.S., and eventually accepted a commission as a Union General.
He distinguished himself as a geographer and cartographer. Not sure if this map of slave density in the South was an early advertisement of a strong feeling against the institution, but given the little that I know about the backstory, it seems plausible.
Pretty early use of choropleth visualization, all-told... and a good one (data normalized by population, in this case) that many makers of modern-day choropleth maps would do well to emulate.
