How to hook events to arbitrary HTML canvas shapes?

Question

JavaScript

Hello. How to hook events to arbitrary HTML canvas shapes? And please advise if you know good libraries for working with 2d graphics in JS. Thank you.

The figures on the canvas are not something tangible, so that they can be hung on them, whether it be events or something else. They cannot be "touched" like nodes in a DOM tree. On the canvas, you only have a coordinate system, and navigate along it.
