Multivariate Map Collection

Here is my attempt to collect examples of multivariate maps I’ve found and organize them into a loose categorization. With this collection, I am just trying to enumerate the various methods that have been attempted, without too much judgement as to whether it is a ‘good’ or ‘bad’ encoding.

Many of these maps are fairly...hideous...but I do appreciate the opportunity to see so many takes on the question "how do I display multi-dimensional geographical data?" The above is my favorite.
