Looks like this component is not compatible with Vaadin 24. I seem to be getting the error:
* class com.vaadin.componentfactory.sparklinerenderer.SparklineRenderer tried to access method 'void com.vaadin.flow.data.renderer.LitRenderer.<init>()' (com.vaadin.componentfactory.sparklinerenderer.SparklineRenderer and com.vaadin.flow.data.renderer.LitRenderer are in unnamed module of loader 'app')
Will see if I can update the source and see if there is a workaround.
