Clutter Reduction

Clutter (caused by too many edges crossing over each other) is a common problem in node-link diagrams.

The following are a few clutter reduction techniques:

• Edge Bundling

• Clustering

• Drawing Edges on Demand (or) Removing the Edges The edges in the above visualization appear on hovering over a node

• Aggregation/Simplification The technique above shows Motif Simplification. The idea is to aggregate together nodes and edges that can be simplified.
