Divided Edge Bundling is a technique that takes a node-link graph diagram and visually simplifies it without the viewer losing the ability to identify directional patterns. It builds off of the Force-Directed Edge Bundling technique by Holten & van Wijk, by taking into account edge direction, weight, and graph topology. The specifics of this technique can be found in our InfoVis 2011 paper.
