Would be nice if you could provide some visual examples of it. Intrested to see how it will look like in the end.

I've heard it said previously that manim is hard to use if you're not 3b1b. Is this (still) true? How hard was the manim side of things to implement, subjectively speaking?

This video shows yacv visualizations of LL(1) and LR(1) parsing. https://youtu.be/BozB0O0__Qg

Since I last used it, it looks like there has been a lot of work on manim in the community fork [1]. It used to definitely be a fair amount of work to figure things out, but it looks like things are easier now. I remember having to dig through source code for everything and the SVG rendering was a nightmare, but since then there's now some proper documentation [2] and an overhaul of how manim does SVG rendering [3]. Looks like it's much nicer to use now. It's worth messing around with if you haven't used manim before
