> For simple graph diagrams it's easy enough to open up a separate graphviz .dot file, write up a graph specification, run it through dot or neato, and include the .png in your markdown file. And then automate this with a Makefile.

Or just use zim ( https://zim-wiki.org/ ) which allows you to embed graphviz diagrams in any 'page', and many other features.
