diagram-design

Create polished, accessible, self-contained HTML/SVG diagrams for architecture, deployment, dependency graphs, workflows, data flows, Sankey flows, sequences, state machines and lifecycle maps, ER and database schemas, UML class, timelines, swimlanes, user journeys, story maps, kanban, Wardley maps, fishbone, charts (bar, waterfall, line, heatmap, treemap, scatter, polar), security views, and other editorial visual types. Redraw Mermaid, draw.io, and Excalidraw sources into a fresh layout, apply optional brand tokens or saved client profiles, add accessible explanatory motion, and verify geometry, accessibility, motion, and single-file safety. Use when the output should be an editable HTML/SVG artifact rather than an ASCII sketch, generated raster image, or editable whiteboard canvas.
