sequenceDiagrams: 
  enable: true
  options: "{theme: 'hand'}"
```

### Options

```js
options = {
  // Change the styling of the diagram, typically one of 'simple', 'hand'. New themes can be registered with registerTheme(...).
  theme: string,

  // CSS style to apply to the diagram's svg tag. (Only supported if using snap.svg)
  css_class: string,
}
```
