Adding graph capabilities

[freemansoft]

I was looking for a graph library for an Advent of Code problem. I ran across the graph library here and realized that I needed to be able to build graphs, and needed more algorithms. Is the tools project looking to add more graph capability? Graph capabilities are outside the normal Dart use case.

I am working on this library and am interested in contributing if there is interest and it adds value https://github.com/freemansoft/fs-dart-tools/tree/main/packages/graphs.
