ABSTRACT
This chapter provides definitions for terminology used throughout the book and introduces some concepts useful for understanding the infrastructure behind any plotly object. The ggplotly() function from the plotly package has the ability to translate ggplot2 to plotly. This functionality can be really helpful for quickly adding interactivity to our existing ggplot2 workflow. Hexagonal binning is useful way to visualize a 2D density9, like the relationship between price and carat. The naniar package provides a suite of computational and visual resources for working with and revealing structure in missing values. The htmlwidgets package provides a foundation for other packages to implement R bindings to JavaScript libraries so that those bindings work in various contexts.
