In this chapter, you learned about the Grammar of Graphics in detail, changing the various theme and color aspects of graphs to create better visuals and reveal further details about data. You also learned how to provide more useful information in scatter plots, using grouping and summarizing to calculate quantities such as the mean, median, quartile, and so on.
In the next chapter, we will work on more advanced plotting techniques, which are not needed quite as often but may be required in some cases.
