Problem

It's not always clear what Matplotlib names things, so it could be really useful if the anatomy figure could be marked up as an svg with links to the relevant user guide sections.

Related to (or alt to) #26205, but building on the idea of using the Anatomy figure as the scoping for the userguide.
