What is Mermaid syntax?

Mermaid is a Markdown-inspired text syntax used to generate diagrams like flowcharts and sequence diagrams. It renders as SVG and is natively supported by platforms like GitHub.

Does this skill support database modeling?

Yes, it provides comprehensive syntax for Entity-Relationship (ER) diagrams, including primary keys, foreign keys, and cardinality notation.

Where can I render the diagrams generated by this skill?

Diagrams generated using this skill can be rendered directly in GitHub READMEs, GitLab, Notion, Obsidian, and VS Code with the appropriate extensions.

Which diagram types can Claude generate with this skill?

Claude can generate flowcharts, sequence diagrams, class diagrams, state diagrams, ER diagrams, Gantt charts, Git graphs, mindmaps, and C4 architecture models.

Is this better than using PlantUML?

Mermaid is often preferred for documentation because it requires zero setup and is natively integrated into most modern Markdown-based developer tools.
