The best use case for me is as explained here: https://koaning.io/posts/svg-gifs/

I like little TIL posts like this, introducing new tools and sharing first-hand experiences with them. Working around restrictions (like using animations in Github Markdown) leads to this kind of creative stuff. I looked at the resulting SVG https://koaning.io/posts/svg-gifs/parrot.svg and realised that a lot of inline SVG elements are used within inline SVG within..the SVG. I've never seen that before. So thank you very much for sharing.

actually, there is a trick that allows you to store the state of your visualisation as you are adding layers. you don't need to have all your data in just one dataframe.
