I once asked about graph processing, (which is loosely? related but more sophisticated than just vectors). I don’t know. Seems more like something in the realm of an extension or community project. Perhaps, it is the reverse of Fun with random curves but that doesn’t look simple either. I do see the Fourier series drawings having the application of closing cartoon curves and colouring them, as shown in previous posts, which is a problem not completely solved in the current implementation.
