PlantUML, Mermaid, Charts... support
I have done an extension of markdown-it to bring all this features with an easy markdown syntax. It is working but in the moment implemented internally in my alinex-report package.
If you are interested I may extract it into its own package to be used within docker, too. But it will bring some bigger dependencies like phantomjs with it which will automatically be installed, too.
Again long time gone I heard nothing from you. I implemented my own documentation tool in this time see https://alinex.github.io/node-codedoc and as mentioned above I can extract the plantuml and mermaid generation tool into a simple markdown-it plugin which you only have to require and install through the use() method to get it to work.
