Supervision and control of wide area transportation networks requires continuous monitoring of large data sets. Two factors complicate the process: data items are spread over a wide geographic area, but are reciprocally influenced through network links, and data types attached to network nodes belong to different categories. We describe a visualization environment that tests the joint use of multiple presentation modes, such as 3D graphics, color, and windowing, to address both factors.
