Documentation of VisualizationsForVaadin

I have just started using this add-on and whilst I appreciate the simplicity of implementing and utilizing it I wonder if there’s any room for customization.

Do you know of any documentation or working example other than the demo on the add-on page?
I’m looking for a documentation of the options you can set to the VisualizationComponent and any other information regarding this add-on really.

I’m thankful for any information I can get!
