Learning Objectives
1. You can visualize relationships between numerical variables using scatter plots with geom_point().
2. You can use color as an aesthetic argument to map variables from the dataset onto individual points.
3. You can change the size, shape, color, fill, and opacity of geometric objects by setting fixed aesthetics.
4. You can add a trend line to a scatter plot with geom_smooth().
