mermaid

Here are the essential rules for creating Mermaid diagrams that render well in GitHub Markdown:

1. Use the Correct Fenced Code Block:

   • Always start the block with mermaid and end it with .

   • 
     ```mermaid
     
       graph TD
     
         A[Start] --> B{Decision};
     
         B -- Yes --> C[Action 1];
     
         B -- No --> D[Action 2];
