Figure 11-5:
Without the application of community-oriented visualization
techniques, large graphs tend to look like meaningless hairballs.
Tip
If your graph has a hairball problem, you will need to tease out clusters
visually through the use of layout, color, and other techniques.
Layouts that Cluster
The term
cluster
by definition implies a spatial relationship. In common
usage, the term is understood to mean a group of similar entities positioned
(or occurring) closely together. Typically, in cluster algorithms as well the
relative similarity of elements is represented mathematically as a distance.
