Graph theory: Weighted edges, loop edges

[GraxCode]

Hello. I would like to animate several algorithms used in computer science. I've noticed it is not possible to add loop edges (edge from a node to itself) and it is not possible to assign weights to edges (decimal numbers). Can you add this functionality?

This should definitely be something that works in the future. Maybe we can manage to do it in the same style that tikz does it.

I think that would be a good idea.

@GraxCode Hey, I would like to know more about this issue. Like is it just writing a logic in python or should we animate it?

Hello,
I have been working on this issue for the past one and a half week and I think I have an implementation that could work fine.
I made a pull request today (#3945) so feel free to give some feedback!
