Line9 is a new rendering engine for Mermaid flowchart diagrams that aims to remove the need for manual adjustment of layout. Mermaid is a popular text-based language for describing multiple types of diagrams. Several Mermaid rendering engines already exist. Most, like the original mermaid.js, use Dagre or ELK graph drawing libraries to automatically lay out their diagrams. I’ve used Mermaid for the past four years but often recreated my flowcharts in a diagram editor so that I could modify the layout to something that better suited my needs. Use Line9 when you want an automatic flowchart…

Hey HN, I built this tool because my personal diagramming workflow was broken, and I wanted to automate it. When creating diagrams, I have two conflicting needs. For logic and structure, I prefer Mermaid.js here. It’s deterministic, version-controllable, and lets me tweak the logic easily until it matches exactly what’s in my head. For aesthetics, I need the final result to look like a high-end infographic for presentations, which Mermaid (and standard tools) are bad at. Before Nanobanana Pro came out, AI image generation cannot generate good visual presentation for diagrams because it…
