Actually there are two different libraries that do this: - https://github.com/folkertdev/graph-layout - https://github.com/gampleman/elm-visualization/pull/4
I would suggest taking a look at these (both use somewhat of a different approach) and seeing how they fit your needs. Neither of them is published yet, but I plan to ship that PR soon-ish.
