PlantUML has some handy diagrams that are not supported by Mermaid. Mindmaps and WBS, for example.
As a workaround, Kroki can generate a link to svg, which then can be pasted in Obsidian with !() . I actually have a match in espanso to get a deflate + base64 value of a diagram and then add it after the last slash in !(https://kroki.io/plantuml/svg/)
I hope that the Plantuml also supports by Obsidian like Mermaid.
My company adapts the Confluence and most of diagrams are drawn by the Plantuml at work.
With both diagram tools, I can get more fun to use Obsidian.
I would like to bring up that the Entity Relation Diagrams in Mermaid is not what it is in PlantUML. I’m trying to make an ERD for my database, but mermaid doesn’t support adding table column names, types, primary keys and so on like what is available in plantuml
