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.
