Visual simplification algorithms

reseaux-graphes2In recent years, edge bundling techniques (a form of visual aggregation) have become increasingly popular in information visualization for the exploration of large graphs or trail sets.

Bundling techniques try to address the exploration of such datasets by simplifying their display using the visual aggregation of close (and related) edges. This way, clutter is traded off to overdraw, which yields images where the main connectivity patterns in a dataset are denser and separated by more whitespace, thus easier to spot.
