Elixir has a pretty nice graph library as well: https://hexdocs.pm/libgraph/api-reference.html

I've used it to do some dependency resolution for operation ordering.

Thanks for sharing. That looks well done. It has some pathfinding algorithms and the reducer is very neat for traversing the graph. I like that it's based on maps, which could make it more performant than the ets based erlang digraph.
