Briesemeister projection

This Briesemeister projection is a projection of the world map onto the 2D space using deformation mostly in the oceans. The VisDock toolkit has been integrated into this Briesemeister example built with D3.js (found here) by Ilya Boyandin. Using selection and other toolkits, users can query distorted lands represented as path elements, and explore the visualization with Pan & Zoom and Rotate. For more information about VisDock, please cick on the link.
