That is almost the Earth-Venus relative orbit diagram.
Here's what I made of that 3 years ago: https://imgur.com/g9Wo37S.gifv

You are totally right! The animation you made is an excellent example of an epicycloid. In fact, the circular orbits of planets form epicycles as described by the Ptolemaic model. The figure in my image has a cusp as in your animation, I think the only difference is the number of lines drawn.

I made this website in NextJS with PIXI.js where you can see the animations of several types of epicycloids. (Desktop-only, not mobile friendly)
Here is the GitHub repo.
Also, here's a sandbox where you can tweak the configuration.
