Text-to-Diagram

Text-to-diagram converts a natural-language description into a structured visual — a flowchart, sequence diagram, org chart, ER diagram, or mind map. The common trick is that an LLM doesn't draw pixels; it generates diagram-as-code in a syntax like Mermaid, PlantUML, or Graphviz, which a renderer then lays out. That makes the output editable, version-controllable, and easy to regenerate. For SaaS builders in developer tools, documentation, and whiteboarding products, it's a natural feature: "diagram the auth flow" produces a starting point a user can refine, instead of dragging boxes by hand. Practical note: models are good at the structure (which node connects to which) but weaker at layout aesthetics, so lean on the rendering engine for positioning rather than asking the model to place things. Validate the generated syntax before rendering — a single malformed line breaks the whole diagram — and offer a code view so power users can hand-tune.
