  • kroki

    Creates diagrams from textual descriptions!

  • I use https://github.com/yuzutech/kroki in my github actions to build plantuml and other diagrams.

    Also playing with 11ty and this to replace our home grown tooling based on markdown with embedded dot.

  • plantuml-markdown

    Example project showing how to use PlantUML and embed UML diagrams into a GitHub markdown

  • dagre

    Directed graph layout for JavaScript

  • Terrastruct engineer here. The visualization will be open source though I can't say for sure yet whether it'll be with our layout algorithm or with https://github.com/dagrejs/dagre.
