Description

As presented by [Wallinger et al.](https://arxiv.org/abs/2108.05467) and implemented for [JS](https://github.com/schochastics/edgebundle/commit/77af8bbe7202f668100f19a0207bb5d8016d04b4) and [R](https://github.com/mwallinger-tu/edge-path-bundling), would be nice to add a Python implementation of this improved edge bundling algorithm.

Research direction

Start by reading the Wallinger et al. paper and comparing the linked JavaScript and R implementations. Then inspect the datashader repository to determine where an edge path bundling implementation belongs. Done means the improved algorithm is implemented in Python and integrated into datashader with documented behavior and validation against the referenced implementations.
