SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Creating clean, consistent educational diagrams usually requires design tools or manual SVG work. This Skill generates production-quality SVG diagrams with a unified flat design system, output as a single self-contained HTML file that renders in any browser with automatic light/dark mode. ## Core Features & Use Cases - Unified design system: 9 semantic color ramps, sentence-case typography, fixed spacing rules, and CSS classes that auto-adapt to light and dark mode. - Eight diagram types: Flowcharts, structural/containment layouts, API maps, microservice topologies, data flows, physical objects, hub-spoke infrastructure, and dashboard mockups. - 15 tested examples: Ready-made patterns for aircraft structures, chemistry mechanisms, floor plans, CPU pipelines, electricity grids, narrative journeys, and more. - Use Case: Ask for a diagram of an SN2 reaction mechanism, and receive a standalone HTML file with molecules, curved arrows, and an energy profile that you open directly in a browser. ## Quick Start Ask the agent to generate a concept diagram of your subject, for example: create a diagram showing the lifecycle of a banana from tree to smoothie as a standalone HTML file.

FAQPage Schema
How do I generate an SVG diagram as a standalone HTML file?

Load the provided template.html, paste your SVG where the placeholder indicates, and save the result as a .html file. The file opens directly in any modern browser with no server or dependencies required.

What diagram types can this SVG skill create?

It supports flowcharts, structural containment layouts, API endpoint maps, microservice topologies, data flows, physical object diagrams, hub-spoke infrastructure integrations, and dashboard mockups. Fifteen tested examples cover aircraft, chemistry, floor plans, and more.

Does the SVG output support dark mode?

Yes. All colors auto-adapt via CSS classes in the template, so a single SVG renders correctly in both light and dark mode without per-mode variants. Light mode uses 50-fill with 600-stroke; dark mode uses 800-fill with 200-stroke.

When should I use a different diagram tool instead?

Prefer a dedicated architecture-diagram skill for dark-tech software or cloud infrastructure, an excalidraw-style skill for hand-drawn whiteboard sketches, or an animation skill for video explainers. This skill serves as a general-purpose fallback otherwise.

Why does my SVG connector render as a filled black shape?

SVG paths default to fill: black, so every connector path or line must explicitly set fill="none". The validation checklist requires this on all arrow connectors, along with the arrow marker defs block at the start of every SVG.
