Line Graph Support

### Describe your use-case which is not covered by existing documentation.

Does this plugin support line graphs? From the documentation and screenshots it sounds like it does not.
I'm looking for something like this: https://github.com/jenkinsci/echarts-api-plugin/blob/main/etc/images/trend-lines.png

### Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.
