This is Markdown with embedded Mermaid with Markdown inside the box named foo. In VS Code, links are opened in editor. In Jetbrains it unfortunately opens in browser.

    # A Simple Diagram
    
    ```mermaid
    graph TD;
    foo["<b>bold</b> <a href='./pyproject.toml'>./pyproject.toml</a>"]
    ```

We could ask LLMs to generate module diagrams with links.
