I have used both Pikchr and several of the Mediawiki extensions for diagrams (the most recently-maintained of which is https://www.mediawiki.org/wiki/Extension:Flex_Diagrams )

Here is my earliest Pikchr effort: https://lumosql.org/src/not-forking (click to see source.)

Pikchr diagrams are crisp and precise with zero configuration. Mermaid diagrams are difficult to make render as nicely as the screenshots show (https://mermaid-js.github.io ) and easier to confuse with ambiguous syntax.

With the addition of 5 lines Lua, Pandoc now handles Pikchr in Markdown documents: https://groups.google.com/g/pandoc-discuss/c/zZSspnHHsg0/m/m...

Mass resignations and letters about moving away from freenode to a new network in Sweden:

Not-forking avoids duplicating the source code of one project within another project, where the projects are external to each other. It avoids project-level forking by largely automating change management in ways that version control systems such as Fossil, Git, or GitHub cannot.
