This package provides two programs: XGobi and XGvis. XGobi is an interactive dynamic graphics program for data visualization in the X Window System. It is especially designed for the exploration of multivariate data. Its basic plot is a scatterplot, and these are some of the tools available for scatterplot display and manipulation. XGvis is an interactive multidimensional scaling (MDS) program that consists of a control panel to manipulate the parameters of the MDS stress function and an xgobi window for data display. It can be used either for visualization of dissimilarity data, for dimension reduction, or for graph layout. Graph layout is usually done in 2D, but xgvis allows layouts in arbitrary dimensions, 3D being the default. It permits missing values, which can be used to implement multidimensional unfolding.
