D3 Examples - SVG Image

SVG Image
This example is a VisDock integration into a static SVG image. The image consists of multiple layers of SVG path elements. Users can use various selection tools, lasso, rectangle, ellipse and lines to query parts of the image and use the Pan-and-Zoom tool to transform the image for their conveniences. The image was found here on Wikipedia.
