The layered structure of ggplot2 encourages you to design and construct graphics in a structured manner. You have learned what a layer is and how to add one to your graphic, but not what geoms and statistics are available to help you build revealing plots. This chapter lists some of the many geoms and stats included in ggplot2, broken down by their purpose. This chapter will provide a good overview of the available options, but it does not describe each geom and stat in detail. For more information about individual geoms, along with many more examples illustrating their use, see the online and electronic documentation. You may also want to consult the documentation to learn more about the datasets used in this chapter.
