Using Mermaid in Observable Framework for diagrams and flowcharts.
Observable Framework documentation: Library: Mermaid Source: https://observablehq.com/framework/lib-mermaid
Mermaid is a language for expressing node-link diagrams, flowcharts, sequence diagrams, and many other types of visualizations. (See also DOT.) Observable provides a mermaid tagged template literal for convenience. This is available by default in Markdown, or you can import it like so:
import mermaid from "npm:@observablehq/mermaid";
To use in a JavaScript code block:
mermaid`graph TD;
A-->B;
A-->C;
B-->D;
C-->D;`
You can also write Mermaid in a mermaid fenced code block:
```mermaid
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
```
This produces:
graph TD;
A-->B;
A-->C;
B-->D;
C-->D;
Here are some more examples.
