GitHub - armish/coffeewheel: D3 Coffee Wheel visualization ported to R via htmlwidgets framework (original) (raw)

An R Interface to D3-based Coffee Wheel

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:
