Holy cow, look at these incredible hand-drawn data visualizations by W.E.B. Du Bois from 1900.
I admit that I knew and know very little about Du Bois and certainly had no idea that he created such visually unique and careful visualizations. The critic in me wants to say that some of these do not hold to modern best data viz practices, but damn, sometimes you want to get lost in a careful study of data and spend some time with beautiful meaningful graphic design. And that’s what you certainly do with these visualizations.
