Abstract: A method is disclosed for displaying a multiplexed property indicator on a network topology map. A coloration designation specification that specifies property-color designations is obtained. A network topology map that includes devices and links having properties that are specified in the coloration designation specification is displayed. A link or device in the map is wrapped with a multiplexed graphical sleeve that includes a color for each property in the coloration designation specification that the link or device has.

Abstract: An approach for drawing a straight-line graph with minimal cognitive disruption to the user is disclosed. In one embodiment, information defining a first graph comprising a first vertex set and a first edge set is received. A second vertex set and a second edge set are received. The second edge set is added to the first edge set. A second graph is created based on the first vertex set and the first edge set. For each vertex in the second vertex set, one or more neighboring vertices are determined, a first barycenter is determined based on positions of the neighboring vertices in the second graph, a second barycenter is determined based on positions of the neighboring vertices in the first graph, and a vector directed from the first barycenter to the vertex in the second graph is determined. Coordinates of the vertex in the first graph are modified to a final position equal to a sum of the vector and the second barycenter.
