This looks very exciting! Is the code available somewhere?

One important question I have is, do you implement it by putting an SVG 
overlay/property over a single dummy character,
or do you put it on a range of text that *semantically* correspond the SVG 
being displayed?
I strongly recommend the latter model because it makes it possible to blend in 
Emacs,
e.g. you can get cursor movement, selection, copy/yank etc relatively easily.
Just for a started, suppose underlying text is structured as one word 
correspond to and SVG element,
then one can use forward-word backward-word to move between elements.
And there’s much more to explore using other existing structural editing 
command.
On the other hand, overlaying over a single dummy character just sounds like 
inventing
a different, isolated editor emulated in Emacs.

I posted some more in-depth discussion over such issue here

If you find the above proposals compelling, I’m happy to collaborate on it if 
that’s helpful!
I once experimented building a music notation software using the above 
discipline
(character -> note head, word -> chord, sentence -> beamed note, paragraph -> 
bar)
but eventually I abandoned it and get away with MuseScore.

Best,
