Scatterplots

A scatterplot displays the relationship between two continuous variables. Scatterplots are one of the most common types of graphs—in fact, you’ve met scatterplots already in Visualization Basics.

In this tutorial, you’ll learn how to:

• Make new types of scatterplots with geom_text() and geom_jitter()
• Add multiple layers of geoms to a plot
• Enhance scatterplots with geom_smooth(), geom_rug(), and geom_repel()
• Change the coordinate system of a plot

The tutorial is adapted from R for Data Science by Hadley Wickham and Garrett Grolemund, published by O’Reilly Media, Inc., 2016, ISBN: 9781491910399. You can purchase the book at shop.oreilly.com.

The tutorial uses the {ggplot2}, {ggrepel}, and {dplyr} packages, which have been pre-loaded for your convenience.
