I'm looking to create animations for a linear algebra course. I need things like writing and changing equations, including matrices, plotting of 2- and 3-dimensional axes with points, vectors, lines and planes, and so on. The intention is to incorporate the animations into a separate video, to demonstrate and visualize what's being said.

How can I go about creating such animations? I'm ideally looking for a free solution.

I'm aware of 3Blue1Brown's youtube channel and vPython package, but I'm looking for other options. Mostly because I don't like working with vPython.

As an example (I encourage the commenters to make their comments answers), one could use the technology used in Activity 4.1.2 of Austin's linear algebra, which makes some reasonable extensive use of javascript. You can see a bunch of examples together in the PreTeXt sample article and how to make them in the code that goes with it.

You may find some useful things already exist at https://demonstrations.wolfram.com/ but it's not at all clear to me what the copyright situation is for using them for videos.
