Customizing a Fisheye View Algorithm to Preserve the Mental Map

摘要: Frequently, large knowledge bases are represented by graphs. Many visualization tools allow users or other applications to interact with and adjust the layouts of these One layout adjustment problem is that showing more detail without eliding parts graph. Approaches based on a fisheye lens paradigm seem well suited this task. However, many techniques non-trivial implement their distortion often cannot be altered suit different graph layouts. When distorting layout, it desirable preserve various properties original in an adjusted view. Pertinent may include straightness lines, topology, orthogonalities proximities. normally not possible all layout. The type its application should considered when deciding which distort. This paper describes view algorithm can customized In contrast methods, user select technique demonstrated through visualizing structures software systems.
