How to make a drawing board on the site?

Question

Design

Good afternoon! Tell me where to dig what to look for. It is necessary to add to the site the ability to draw, roll back the drawn, erase the drawn with an eraser and delete everything drawn (on top of the content on the site (browser extensions, for some reason they do not draw)). How can I do that? Maybe there are already ready-made codes, or any solutions?
