Visualizing information on a sphere [PDF]
Proceedings of VIZ '97: Visualization Conference, Information Visualization Symposium and Parallel Rendering Symposium, 2002 We describe a method for the visualization of information units on spherical domains which is employed in the banking industry for risk analysis, stock prediction and other tasks. The system is based on a quantification of the similarity of related objects that governs the parameters of a mass-spring system. Unlike existing approaches we initialize all
