D3 Examples - VisDock in Stacked Bar Chart

VisDock in Stacked Bar Chart
The VisDock toolkit has been integrated into this Stacked Bar Chart example built with D3.js (found here) by Mike Bostock. Using selection and other tools, users can query stacked bars made of rectangular elements, and explore the plot closely using Pan & Zoom tools. For more information about VisDock, cick on the link.
