You may check out Pikchr <a href="https://pikchr.org" rel="nofollow">https://pikchr.org</a> tool/language, inspired by the PIC language.<p>It's by the creator of SQLite and Fossil SCM. In fact the Pikchr functionality is bundled into Fossil SCM, and is directly supported in Fossil's UI (can be mixed in Markdown in the docs/wiki/forum).<p>The Pikchr language takes some patience to learn, but there're some useful examples to get you started. Plus, you could ask for help on the Forum.
Last time I had to embed diagrams I used mermaid js <a href="https://mermaid-js.github.io/mermaid/#/" rel="nofollow">https://mermaid-js.github.io/mermaid/#/</a> which is made to be rendered alongside markdown. Not sure if your particular diagram is supported but the project has a big community around it so there should be a way.
