Mermaid is already supported natively, meaning the mermaid diagram output is rendered as actual images; no need for ascii diagrams https://mfontanini.github.io/presenterm/features/code/mermai...

This is great if you are fine managing npm packages, seems the only smooth way to install mermaid-cli. I'd say this is a mermaid limitation not a presenterm limitation.

Yeah, I'd love to not rely on an npm package but it's unfortunately the only way to do this out of the box.
