It seems not support plantuml.

Well, you have to jump some hoops but I got it working:

• Install pandoc. Maybe you already have it installed
• Install the lua diagrams generator files. See the installation section (https://github.com/pandoc/lua-filters#installation)
  • Basically you need a location locally where all the lua files from that project are saved.
  • From their example they would end up in: /home/username/.local/share/pandoc/filters
  • Install Java. More likely you have it already installed
  • Download the plantuml.jar from plantuml. See: https://plantuml.com/starting

Assuming you have everything installed correctly, then in the Export Setting of the Obsidian plugin, edit the Extra arguments to something like:

--lua-filter=/home/username/.local/share/pandoc/filters/diagram-generator.lua --metadata=plantumlPath:"/usr/share/java/plantuml/plantuml.jar"

and it works!!!

I already said, it is kinda involved, but it does work!

@stratosgear A better solution: https://github.com/pandoc-ext/diagram , but I'm not tried it.
