Org Charts in Vaadin 7

I would like to have a interactive org chart in Vaadin 7. There was an integration addon - vaadin visualisations but it only support vaadin 6.

https://vaadin.com/directory#addon/visualizationsforvaadin

I would consider using google charts or some js widgets. Any other suggestions ? Whats the best approach ?
