Render clean blueprint-style SVG diagrams from JSON specs. Use when users ask to draw, sketch, or diagram a request flow, neural net, transformer block, system architecture, state machine, data pipeline, or any node-and-edge technical visual they want as an SVG for docs, READMEs, posts, or slides.

From the source SKILL.md

Use diagrammer to turn a small JSON spec into a clean SVG diagram. It is useful when the user wants a precise technical diagram without opening a design tool.
