Frequently Asked Questions about mermaid-chart

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate flowcharts and diagrams from text descriptions?

To generate flowcharts from text, you write Mermaid syntax descriptions which the skill renders into source `.mmd` files and visual `.png` images. This automates diagram creation without needing complex graphical tools.

Do I need Mermaid CLI installed to render sequence diagrams and ER diagrams?

Yes, you need Mermaid CLI installed to render sequence diagrams and ER diagrams. The skill depends on the `@mermaid-js/mermaid-cli` package to convert Mermaid text syntax into rendered PNG image files.

What types of diagrams can I create using Mermaid syntax?

Using Mermaid syntax, you can create flowcharts, sequence diagrams, class diagrams, ER diagrams, state diagrams, Gantt charts, pie charts, git graphs, mindmaps, timelines, C4 diagrams, and block diagrams from textual descriptions.

How do I save generated Mermaid diagrams to a specific directory?

To save generated Mermaid diagrams, you specify an output directory path. The skill defaults to saving the generated `.mmd` source files and `.png` rendered images into a `docs/` directory within your project structure.

What is the best way to visualize a database schema without using graphical tools?

The best way to visualize a database schema without graphical tools is generating an ER diagram using Mermaid text syntax. The skill processes your text descriptions to output ready-to-use `.mmd` and `.png` files.

Are there limitations when rendering Gantt charts or mindmaps from text?

Limitations when rendering Gantt charts or mindmaps depend on the Mermaid CLI rendering engine. The skill outputs `.mmd` and `.png` files but requires the `@mermaid-js/mermaid-cli` dependency to function properly.
