The picture shows the number of fairs and markets per year, in 1732, in the Occitania region in the south of France (where I live). The small blobs denote three fairs per year, the biggest one, 13. I’ve decided to perceive the picture as a visualization of two things: street life intensity, and infrastructure for small-area food distribution. Please send me your nominations for social infrastructure graphic of the year (which we’ll show in Delhi).
