The R package \href{http://docs.ggplot2.org/current/}{ggplot2}
is a plotting system based on the grammar of graphics. \href{https://
ggobi.github.io/ggally}{GGally} extends ggplot2 by adding several functions to
reduce the complexity of combining geoms with transformed data. Some of these
functions include a pairwise plot matrix, a scatterplot plot matrix, a parallel
coordinates plot, a survival plot, and several functions to plot networks.
