beautiful-mermaid

Render Mermaid diagrams to SVG, PNG, or terminal ASCII through the bm CLI from beautiful-mermaid-cli.

When to use

• The user wants to render a Mermaid diagram (graph, flowchart, sequenceDiagram, classDiagram, stateDiagram, erDiagram, gantt, …) to an image file.
• The user pastes Mermaid source and asks for a rendered visual.
• The user wants ASCII / Unicode box-drawing output for a diagram in the terminal.
• The user asks to render with a specific font, or to know which fonts are available — first call bm fonts --json to enumerate the system, then pass --font <family> (or --font-file <path>) to bm render.

Prerequisites

Confirm the bm binary, fonts, and PNG WASM runtime are usable before rendering programmatically:

bm doctor --json
