The VisDock toolkit has been integrated into this Zoomable Circle Packet example built with D3.js (found here) by Mike Bostock. Selection tools can be used to query circle node elements in the diagram. Annotations, Pan & Zoom tools and VisDock lenses can be used to help explore the interactive visualization.
