Line9 is a new rendering engine for Mermaid flowchart diagrams that aims to remove the need for manual adjustment of layout.

We set out to build this originally for OpenKnowledge, our markdown wysiwyg editor, then realized it’d be great to share it as a proper embeddable component library so that other apps can leverage it as well. Our general take is that AI is great for generating…
