I am not sure whether GitHub would have notified you of this, but I opened and accepted an instance of this pull request in my fork (which was originally made precisely to have a version with fixes from issues and PRs).

The fork has now been detached and released as its own library, altair-nx, because the original has been inactive since 2020 and because the fork diverged from it considerably after a full code-base rework and the implementation of new features (e.g. curved edges, self loops, and much greater customisability).
