Mermaid Diagram Builder

Creates clear, valid, version-controllable diagrams as code using Mermaid — flowcharts, sequence diagrams, ER diagrams, class diagrams, state machines, Gantt charts, C4/architecture diagrams, and more. Use this skill when the user asks to "draw a diagram", "make a flowchart", "create a sequence diagram", "diagram this architecture", "visualize this process/data model/API flow", "show the ER diagram", "render Mermaid", "diagram as code", or wants a chart embeddable in Markdown, GitHub, Notion, or docs. Covers picking the right diagram type, writing syntactically correct Mermaid, styling, and validating that it renders.
