[`ggplot2`](https://ggplot2.tidyverse.org/) is a plotting system for R based on the grammar of graphics. [`GGally`](https://ggobi.github.io/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.
