Over flow: An overview visualization for network analysis
msra(2009)
摘要
Many network visualizations make the assumption that an administrator has previously determined the subset of data that should be visualized. Yet the problem remains that if the visualization provides no insight into the network events that warrant further consideration, then the administrator must go back to the data to determine what should be visualized next. This is a critical issue given the amount of network data under consideration, only a small portion of which can be examined at any one time. In this paper we present a visualization that provides context for network visualizations by providing a high-level view of network events. Our visualization not only provides a starting point for network visualization, but also reduces the cognitive burden of the analyst by providing a visual paradigm for both the filtering of network data and the selection of network data to drill into and visualize with alternative representations. We demonstrate, through the use of a case study, that our visualization can provide motivation for further investigation into anomalous network activity.
