Web Reference: Out of these components, ggplot2 needs at least the following three to produce a chart: data, a mapping, and a layer. The scales, facets, coordinates, and themes have sensible defaults that take away a lot of finicky work. Learn ggplot2 data visualization in R from the ground up. Covers layers, aesthetics, geoms, and facets with clear examples and reusable code. In this chapter, you’ll dive into the details of a layer, and how you can control all five components: data, the aesthetic mappings, the geom, stat, and position adjustments. The goal here is to give you the tools to build sophisticated plots tailored to the problem at hand.
