Album de Statistique Graphique

What stands out to me (other than this being an amazing collection, especially as a big Edward Tufte fan) is the use of radial/web diagrams.

The idea that variables can have relationships in more than 2-dimensions seems to have been lost.

I'm actually using a d3 version of these for a blog post I'm working on about machine learning and data companies, and the example code for creating beautiful radial charts (not mine) can be found here: https://github.com/kolektiv/maturity-radar

As someone who has developed a product that uses Sankey diagrams to represent complex relationships, this catalogue from the past gives me some hope for the future. :)
