Hive Plots - Rational Network Visualization — Farewell to hairballs

http://mkweb.bcgsc.ca/linnet/

The hive plot is a rational visualization method for drawing networks. Nodes are mapped to and positioned on radially distributed linear axes based on network structural properties. Edges are drawn as curved links. Simple and interpretable.

The purpose of the hive plot is to establish a new baseline for network visualization. Unlike hairballs, hive plots are excellent at managing the visual complexity arising from large number of edges and exposing both trends and outlier patterns in network structure.
Summary

Network visualizations are notoriously difficult to interpret. Their canonical representation in a visual form is the so-called hairball, which can be accidentally informative, but cannot be relied upon to consistently reveal meaningful patterns.
