a post with diagrams

This theme supports generating various diagrams from a text description using mermaid. Previously, this was done using the jekyll-diagrams plugin.

To enable mermaid, you have to put the following in this post frontmatter:

mermaid:
  enabled: true
  zoomable: true

To disable the zooming feature, set mermaid: zoomable to false.

The diagram below was generated by the following code:

```mermaid

    participant John
    participant Alice
    Alice->>John: Hello John, how are you?
    John-->>Alice: Great!
```

    participant John
    participant Alice
