I tried an epub version of "SVG 1.1 2nd Edition Test Suite" a few years ago, but that was not helpful. By the way, I can't find this book now, only W3 web pages with individual tests.

I may eventually put together an epub written specifically to try all the suggestions here plus everything else I can think of.

I must say that I am very disappointed that HTML with simple references to PNG and JPEG image files works just fine in epub readers, but not for SVG in most epub readers on e-ink devices, including FBreader. Especially since they work fine in desktop FBreader and ipad and even somewhat in epub converted to azw3.
I just tried the file you attached loaded on my Kobo Aura One via. Calibre and the KoboTouchExtended plugin(so as a kepub) on the latest firmware. It seems to load the diagrams fine. Although they are pretty small on the screen.

It looks like this.
