If you’re not familiar with it, the Western Front was a major line of battle between France and Germany during World War I. It was effectively a stalemate, with the line never moving much during the duration of the war, but a huge number of people died along it.
Mandy sent me a link to some amazing maps with various bits of data from the War. The one shown above is a segment of a map overlaying exhumed bodies on top of what’s a mostly standard map.
It’s a sad display, but a wonderful expression of multi-variate data display. Tufte would be proud I think.
