Applied Data Visualization with R and ggplot2

Changing Boxplot Defaults Using the Grammar of Graphics

In this section, we'll use the Grammar of Graphics to change defaults and create a better visualization.

Let's begin by implementing the following steps:

1. Use the humidity data to create the same boxplot seen in the previous section, for plotting monthly data.
2. Change the x- and y-axis labels appropriately (the x-axis is the month and the y-axis is the humidity).
