Deze reeks bevat enkel leesopdrachten en kan een goeie inspiratiebron zijn voor het maken van plots. De reeks is optioneel.

In this chapter, we will demonstrate how relatively simple ggplot2 code can create insightful and aesthetically pleasing plots. As motivation we will create plots that help us better understand trends in world health and economics. We will implement what we learned in Chapters 7 and 8.16 and learn how to augment the code to perfect the plots. As we go through our case study, we will describe relevant general data visualization principles and learn concepts such as faceting, time series plots, transformations, and ridge plots.
