Adding a title to your graph
There are many other options for customizing a ggplot2 graph, which you can learn about in other DataCamp courses. You can also learn about them from online resources, which is an important skill to develop.
As the final exercise in this course, you'll practice looking up ggplot2 instructions by completing a task we haven't shown you how to do.
