Creating a Scatterplot of Two Continuous Variables

Let's now create scatterplots using geom_point() and geom_().

1. Create a scatterplot of the bodywt and sleep_total variables from msleep:

ggplot(msleep, aes(bodywt, sleep_total)) + geom_point()

2. This scatterplot is a great candidate for using geom_jitter(), as many of the sleep_total observations cluster around the zero bodyweight. We'll use a fairly large width for jitter to really separate these points, because the scale of bodywt is in the thousands:

ggplot(msleep, aes(bodywt, sleep_total)) + geom_jitter(width = 50)

Output: The following is the output we get when we execute the code mentioned in Step 1:
