ggforce: Accelerating ggplot2

Description

This package contains a range of useful stats, geoms, trans and utilities to get more out of ggplot2. Many of the additions are mainly aimed at developers wanting to develop new visualizations using ggplot2 rather than statisticians wanting to understand their data.
