At some point in the past I've experimented with
https://tikzjax.com/
So I changed something somewhere in the org-mode config and it just worked, it 
was quite straightforward to do. I however probably don't have notes on how I 
did it.
I didn't insist in that direction because it wasn't working with TikZ libs, 
specifically tikzcd.
But it was really nice.
This however is implementing many TikZ libraries, I don't know if it's usable 
with org-mode, but it looks totally great, it's from Obsidian but it's on 
Github
https://github.com/artisticat1/obsidian-tikzjax
IMO this sort of solution is very nice.
