You can use imageMagick to create pictures from scratch. As it’s a parameters configuration, and the exemple you gave are frameworks based.

But I prefer create pictures with SVG, it has animation, interaction…, this kind of programmation is more permisive and portable 😂.

PS : to complete the author’s message : Manim

All receivers (I call client) must get all the files from the source (I call server) ?

Then, does the clients are known ? (Example : you can access, or you can left a tutorial and they can install a new software)

If yes for all files :
Git could work, but you have to host the server, cause no free online website do allow big content.

If no for all files : Then a solution could be to share with https://zeronet.io/

This post is not done writing, i’ll complete later.

Because people are lazy.
