Figure 14-9: Tiled geospatial network plots are a seamless fit with map
systems. Here, Twitter activity of millions of users is overlaid on a map,
where graph links represent user travel to different locations.
Community Visualization
Another case when depicting all of the data in a very large graph is useful
is for understanding communities. This is, in fact, a primary use case for
graphs on the scale of thousands of nodes as well, as reflected in many of the

extensive interaction.
An effective approach for community visualization is to use community
detection algorithms to aggregate nodes hierarchically by community.
