Manim is a really useful tool that allows you to create animations and illustrations programmatically, which is a much nicer experience than doing it by hand in Blender.
Manim is mostly known by its creator, 3Blue1Brown, but is now maintained by the community as the community edition.
I would make and post Manim animations on this website, but I dont have the time or the patience, and desmos works fine for what I do.
