Renamed to digital-society-coop/elm-tree-layout. It is published under that name, and new versions come out there.
Versions published as wasdacraic/elm-tree-layout still install under that name. 2 versions of 2 come from the new location (see their notes).
Rerouted (renamed, verified). The GitHub user or repository was renamed. The tag is still there, at the new name. The Lamdera package server serves a copy recovered from https://github.com/digital-society-coop/elm-tree-layout.
What we checked: The repo moved to github.com/digital-society-coop/elm-tree-layout. Rebuilt with git archive from commit 60cb32d445cc of https://github.com/digital-society-coop/elm-tree-layout (zip prefix wasdacraic-elm-tree-layout-60cb32d/, America/Los_Angeles times): the zip is byte-identical to the one package.elm-lang.org recorded, SHA-1 a1c9d2b1b3dc78d0a247543ca948fbc09ccf7c80.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.

Return x and y coordinates for a general tree, layed out according to aesthetic rules defined by (Walker, 1989). This implementation is based on the pseudo-code given in the improved algorithm that runs in linear time by (Buchheim, Junger and Leipert, 2006).
While providing the coordinates, this module does not render the tree to keep it generic.
Return a dictionary of x and y coordinates keyed by a unique identifier for a node for a given 'distance' (used as a constant for x spacing) and 'nodes' (a list of hierarchy descriptors starting with the root, represented by tuples of node identifier and parent node identifier).
Note: The x coordinates will have negative values, as the root node will always be at 0. The y coordinates will be integers from 1 to the max depth of the tree.
