Abstract
Directed graphs are used in a significant number of applications for visualizing concepts and relationships. This paper describes research in knowledge-based editors for the direct, visual manipulation of such graphs. The novel aspects of this work are: (1) The editor produces an aesthetically pleasing layout of the graph automatically, freeing the user from cut-and-paste work after changes. (2) The editor can be adapted quickly to a particular application. (3) The editor can invoke application-specific functions for processing the graph while it is being manipulated.
We first present kb-edit, a prototype editor that demonstrates the knowledge-based approach. We then describe current work on EDGE, a new graph editor that provides a more extensive set of methods for controlling the display, for example graphical abstraction, 2 1/2-D display, semi-automatic layout, display of edge attributes, and graph animation.
