This is an htmlwidgets-based visualization tool for hierarchical data. It is zoomable, meaning that you can interact with the hierarchy and zoom in/out accordingly. The visualization is D3-based and the actual wheel visualization code is adapted from:

This package is currently not on CRAN, but you can install it from GitHub via devtools:
library("devtools");
devtools::install_github("armish/coffeewheel");library("coffeewheel");
