diagram-maker

name diagram-maker description Create SVG/HTML or Excalidraw diagrams for concepts, architecture, flows, and whiteboards. metadata {"openclaw":{"emoji":"🧭"}} Diagram Maker Create diagrams as artifacts, not prose. Choose one output mode: clean-svg : educational concepts, physical systems, processes, lifecycle, simple data flow. architecture-svg : software/cloud/infra topology, services, databases, queues, trust zones. excalidraw : editable hand-drawn whiteboard, flowchart, sequence, architecture sketch. Routing User wants editable/collaborative: choose Excalidraw. User wants polished standalone browser output: choose SVG/HTML. Software architecture with infra components: choose architecture SVG. Science, product, process, concept map, physical object: choose clean SVG. Unsure: ask one short question only if output format matters; otherwise choose clean SVG. Workflow Extract nodes, groups, labels, and directed relationships. Pick layout first: left-to-right, top-down, hub-spoke, swimlanes, layered stack, sequence. Keep labels short. Prefer 5-9 main elements over dense diagrams. Generate the file at the requested path, or ./diagram.html / ./diagram.excalidraw . Verify syntax by opening/parsing when feasible. SVG/HTML rules Single standalone .html file with inline CSS and inline SVG. No external fonts, JS, images, gradients, glows, decorative blobs, or remote assets. Use semantic colors, not rainbow sequences: neutral, input, process, storage, external, risk. Draw connectors before nodes so arrows sit behind boxes. Every connector path has fill="none" and a marker arrow when directed. Leave 24px text padding inside boxes; do not let text touch borders. Legend only when symbols/colors are not obvious. SVG template Use references/svg-template.md as the wrapper and replace <!-- SVG --> . Excalidraw rules Save .excalidraw JSON with type , version , source , elements , and appState . Use bound text for shape labels. Do not use a nonstandard label property. Keep bound text immediately after its container in the elements array. Minimum labeled shape: 120x60. Minimum body text: 16px. Use roughness 1 , fontFamily: 1 , and simple fills. For exact Excalidraw element snippets, read references/excalidraw-patterns.md .
