Graphs have a very natural visual representation as nodes and connecting links arranged in space. Although many examples show the computational manipulation of large data sets that can be expressed in graph form, visual representations of them as graphs are not common. Current tools are inadequate for the job: conventional systems are often challenged by hundreds of edges, and none can handle more than a few thousand edges. However, nonvisual manipulation of graphs with 50,000 edges is commonplace, and much larger instances exist. A graph drawing system that focuses on the interactive browsing of large graphs can be targeted for the quite different tasks of browsing and exploration. Many researchers in scientific visualization have recognized the split between explanatory and exploratory goals. This distinction is equally relevant for graph drawing.
