D3 Examples - VisDock in Normalized Stacked Bar Chart

VisDock in Normalized Stacked Bar Chart

The VisDock toolkit has been integrated into this Stacked Bar Chart example built with D3.js (found here) by Mike Bostock. This example is similar to another stacked bar example with VisDock, which can be found here. This example requires only very small change to the original source code. 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.
