drawio
Desktop-first Draw.io diagram creation, editing, replication, and conversion (redraw, remake) with a YAML design system supporting 6 themes. Use when creating visual diagrams, drawings, figures, schematics, charts, system architecture diagrams, network diagrams, flowcharts, UML, ER diagrams, sequence diagrams, state machines, org charts, mind maps, cloud infrastructure diagrams, research workflows, paper figures, IEEE-style diagrams, or diagrams containing formulas, equations, LaTeX, AsciiMath, MathJax, inline math, block math, or other mathematical content. Accepts Mermaid, CSV, and YAML input; convert to draw.io from mermaid or any structured source. Defaults to offline/local generation with .drawio files plus metadata sidecars; use the optional next-ai MCP only when live browser editing is genuinely needed.
