Key function: geom_bar(). First, you need to tell ggplot what dataset to use. Here we visualize the distribution of 7 groups (called A to G) and 2 subgroups (called low and high). In a line graph, observations are ordered by x value and connected. These plots are suitable compared to box plots when sample sizes are small. In this chapter, we’ll show how to plot data grouped by the levels of a categorical variable. Bar charts are useful for displaying the frequencies of different categories of data.
