Diagram Creator — Claude Code Skill
Turn any input into beautiful, production-ready diagrams on an infinite canvas. Self-contained HTML files with 5 themes, 8 topology layouts, pan & zoom navigation, professional typography, smooth animations, and zero dependencies.
What It Does
Give it literally any file — or just a sentence — and it generates a polished diagram as a single .html file you can open directly in your browser. No accounts, no setup, no dependencies.
"Create a diagram of OAuth 2.0 flow" → diagram-oauth2-flow.html
"Visualize this docker-compose.yml" → diagram-docker-compose.html
"Diagram my Kubernetes networking" → diagram-k8s-networking.html
"Turn this business plan into a visual schema" → diagram-business-plan.html
The skill reads any file, auto-detects the format, extracts the relevant structure, and picks the best topology and layout. You don't need to reformat your input — just point it at a file and it figures out the rest.
Supported Inputs
Give it any file or topic — code, config, data, docs, PDFs, spreadsheets, notebooks, API specs, database schemas, CI/CD pipelines, or just a sentence describing what you want. The skill reads the content, auto-detects the format, extracts the relevant structure, and diagrams it. No reformatting needed.
8 Topology Layouts
| Layout | Best for | Examples |
|---|---|---|
| Nested | Hierarchical containment | Docker networking, K8s pods, VPCs, OSI model |
| Left-to-right | Sequential flows | OAuth flow, CI/CD pipeline, user journey |
| Hub-and-spoke | Central node + surrounding nodes | API gateway, microservices, load balancer |
| Timeline | Ordered vertical steps | Deploy pipeline, project roadmap, historical events |
| Grid / Matrix | Comparison tables, feature grids | Feature comparison, skill map, competitive landscape |
| Tree / Org Chart | Hierarchical branching | Org chart, file tree, decision tree, taxonomy |
| Funnel | Progressive narrowing | Sales funnel, conversion pipeline, data filtering |
| Comparison / VS | Side-by-side 2-3 options | Product vs product, tech choices, before/after |
5 Themes
| Theme | Best for |
|---|---|
| Dark (default) | Technical diagrams, dev docs, README screenshots |
| Light | Presentations, documentation sites, print-friendly |
| Corporate | Business plans, pitch decks, stakeholder presentations |
| Neon | Creative projects, gaming, social media screenshots |
| Minimal | Clean documentation, technical specs |

"Diagram this file: /path/to/architecture.md"
"Visualize /path/to/docker-compose.yml"
"Turn /path/to/schema.prisma into a diagram"
