## Configuration

Configure for all home and regular pages:

```toml
[params.flowchartDiagrams]
  enable = true
  options = ""
```

Configure for a single post in the front matter (**Params in front matter have higher precedence**):

```yaml
flowchartDiagrams:
  enable: true
  options: "{
              'x': 0,
              'y': 0,
              'line-width': 3,
              'line-length': 50,
              'text-margin': 10,
              'font-size': 14,
              'font-color': 'black',
