Throughout this book so far, nodes have existed outside of any particular time or space. In visualizations, nodes have been placed on a two-dimensional space (pages), but only because it would be difficult to tell them apart if they were all on top of each other. In some cases, nodes truly are associated with a particular spatial location or a particular time. In these cases, additional techniques can be helpful for visualizing and analyzing networks. This chapter describes some of the special techniques needed for networks in space and time and applies them to real-world examples, including airports and links on Wikipedia.
Topics in this chapter include the following:
- Locations and events: Explaining how networks can be used to represent data with temporal and spatial properties
- Networks in space: Visualizing and analyzing relationships between locations...
