Visualization with XGobi, XGvis & GGobi

High dimensional data presents many problems related to the tasks of viewing and navigating. One of the first stats oriented software package to address these issues was AT&T’s interactive visualization system, Xgobi http://www.research.att.com/areas/stat/xgobi/. Xgobi is not a stats package per se. Instead Xgobi provides various 1D, 2D and 3D displays in ways that use linkage(brushing) between displays, data IDs and various projection methods such as Grand Tours and Projection Pursuit. XGivs is an interactive MDS, MultiDimensional Scaling, package for proximity data as well as graphical networks. Note, the AT&T URL is a historical reference, but current and new developement of xgobi is now called GGobi, http://www.ggobi.org/.
