What are the best approaches for turning an image into a plottable vector graphic?

There are a lot of options for this but the two I really like are https://github.com/SonarSonic/DrawingBotV3 and https://mitxela.com/plotterfun/

Also, vpype (https://github.com/abey79/vpype) isn't specifically a tool for vectorizing images, but its incredibly useful for preparing vector files for plotting.

I made this some time ago: https://github.com/serycjon/vpype-flow-imager
