format-diagram

Generate branded diagrams (process flows, architecture views, stakeholder maps, org charts, timelines, funnels, matrices, mind maps, sequence/state/ER/gantt) as SVG/PNG for embedding in PPTX, DOCX, PDF or deck deliverables. Author Mermaid text and call the server-side render_diagram tool (auto-layout, deep brand theming, works in a deployed sandbox, brand-gated). Use when asked to draw, map or visualize a process, structure, workflow or relationship. Not for numeric data charts (use format-chart) or plain Mermaid syntax for a README, wiki or Markdown page (use format-mermaid).
