I've searched around and not found much about animation. I'd like to make an animation out of interpolations. It takes far too long to do this manually. Are there tools to speed up the process?

While you are waiting for someone who knows animation better than I, I'll just comment that yes, it does work to make animations out of interpolations. I think I followed both a Youtube video and some threads here (but this was a couple of yrs ago, they could be gone by now). What I found to have worked the quickest was to make the drawings on here, use interpolation, then go to GIMP to finish the process. It was fairly easy to do, just takes a lot of space.

Any other ideas?

It might be possible if the beginning object's and the end objec's topology are the same I guess.
I was searching for creating animated svg as the svg standard supports animations.
You can do that by writing in the codes of the svg with a notepad.
There are ways to include other languages in the document too, like ecmascript and javascript.

I couldn't get along with the basics though.
