SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Diagramming complex architectures, data flows, and user journeys can be time-consuming and error-prone when done by hand. Mermaid v11 provides a lightweight, text-based approach to generate clear, reusable diagrams that render across common Markdown viewers.

Core Features & Use Cases

  • Diagram variety: supports flowchart, sequenceDiagram, erDiagram, journey, and gantt in Mermaid v11.
  • Markdown-friendly rendering: diagrams render in Markdown viewers (GitHub, Obsidian, Docusaurus, etc.).
  • Use Case: quickly illustrate a feature's data flow from user action to API and database, or map a system component relationship for docs and planning.

Quick Start

Provide a Mermaid code block with the chosen diagram type and node definitions to render.

FAQPage Schema
How do I generate Mermaid v11 diagrams for software architecture and data flows?

You can render Markdown-friendly Mermaid v11 diagrams by providing a code block with the chosen diagram type and node definitions. This outputs text-based diagrams that display correctly across Markdown viewers like GitHub, Obsidian, and Docusaurus.

What diagram types are supported in Mermaid v11 syntax for documenting system topology?

Supported Mermaid v11 diagram types include flowchart, sequenceDiagram, erDiagram, journey, and gantt. These allow you to illustrate feature data flows from user action to API, or map system component relationships for documentation.

Can I use Mermaid diagrams to document feature planning in Markdown viewers like GitHub and Obsidian?

Yes, Mermaid v11 diagrams render in Markdown viewers including GitHub, Obsidian, and Docusaurus. The text-based approach produces clear, reusable diagrams that visualize architecture and data flow across common Markdown platforms.

What is the maximum number of nodes allowed when generating a Mermaid flowchart or sequence diagram?

Mermaid diagram generation is constrained to within 15 nodes per diagram. This limit ensures clear, reusable diagrams that render effectively across Markdown viewers when visualizing complex architectures and data flows.

Why use text-based Mermaid diagrams instead of manual drawing for mapping system interactions?

Text-based Mermaid diagrams avoid the time-consuming, error-prone nature of manual diagramming. They offer a lightweight approach to generate clear, reusable architecture, data flow, and user journey diagrams that render across Markdown viewers.
