Mermaid Diagram Examples

This page demonstrates how to use Mermaid diagrams in MDX files. Mermaid is a JavaScript-based diagramming and charting tool that renders Markdown-inspired text definitions to create diagrams dynamically.

Basic Usage

To add a Mermaid diagram, simply use a code block with the mermaid language:

```mermaid
graph TD;
    A[Start] --> B{Is it working?};
    B -->|Yes| C[Great!];
    B -->|No| D[Debug];
    D --> B;
    C --> E[Deploy];
```

Which renders as:

```mermaid
graph TD;
    A[Start] --> B{Is it working?};
    B -->|Yes| C[Great!];
    B -->|No| D[Debug];
    D --> B;
    C --> E[Deploy];
