Show HN: DAG-map – metro map visualization of a DAG (23min.github.io)

I searched for a library that promised the kind of layout and esthetics that I was after. This has been a recurring "issue" for me where I have something very specific in mind but can't seem to be able to mold anything existing into what I want.

Inspired from metro maps, like the London Underground, I wanted something that captures "stations" for crossings (fan-in, fan-out or processing nodes) and a left to right flow that, in my DAGs, often represent the flow of time.
