Description

Is it possible to draw curved edges connecting two nodes? For instance I want an edge that wraps around from the end of a row back to the beginning.

This is accomplished in TikZ by specifying the outgoing and incoming angle for an edge relative to the start and end nodes. Is there a similar feature in Matplotlib that could be added to the Edge class?

Contributor guide

Research direction
Examine the existing Edge class to understand how edges are currently drawn. Then research matplotlib's arc drawing capabilities and consider adding parameters for outgoing and incoming angles to enable curved edges.
