I certainly get your point, nevertheless I am a bit confused by your example, because PlantUML should work out of the box.

Ah good point. Sorry, looks like syntax might have changed since I last had this asciidoc open (it's been a couple years)? ditaa and uml seem to be working after all.

Might be good to explicitly note which extensions are pre-installed, and which need extra work?
Looks like Mermaid needs some help? installed via npm, but complains about PATH, even after adding to path. Added to document variable, but hits:

Failed to generate image: mmdc failed: file:///home/gstewart/node_modules/@mermaid-js/mermaid-cli/src/index.js:262
      const svg = container.getElementsByTagName?.('svg')?.[0]
                                                 ^
