the challenges, however, can be that the limited capability to move nodes
can make it more difficult to make links easily readable. In Figure 2-16 ,
a fictional subway map demonstrates how schematic versions of spatial
network graphs can abstract angles and locations for legibility.
Figure 2-16: Schematic network diagrams abstract spatial layout to
optimize legibility, as in the route map shown here.
In addition to showing how network routes and hubs are connected, graphs
can also show performance characteristics of those routes and hubs. Figure
2-17 shows average winter flight delays for all airline routes flying in and out
of airports across the United States. Red routes and airports indicate greater
delays. The size of route and airport indicate the number of flights.
