drawio-diagrams

**WORKFLOW SKILL** - Create, validate, and edit accessible draw.io SVG diagrams that remain visually editable. Supports basic flowchart and architecture shapes, semantic styling, orthogonal connectors, strict specification validation, and embedded mxGraph XML. USE FOR: create a draw.io diagram, create a .drawio.svg, make an editable architecture or flow diagram, validate draw.io XML, use diagrams.net. DO NOT USE FOR: quick throwaway diagrams that do not need draw.io editability; use Mermaid instead, or complex cloud/UML diagrams that require full draw.io shape libraries; use draw.io Desktop or jgraph/drawio-mcp.
