This is an R package as the next generation of GGobi, a software
package for interactive and dynamic statistical graphics. It includes most
of features in GGobi such as brushing, zooming, panning, identifying and
linking, as well as common types of statistical graphics, e.g. bar plot,
scatter plot, boxplot, histogram, density plot, spine plot, parallel
coordinates plot, mosaic plot, maps, missing value plot, time series plot,
