Learning Objectives
1. You can create line graphs to visualize relationships between two numerical variables with geom_line().
2. You can add points to a line graph with geom_point().
3. You can use aesthetics like color, size, color, and linetype to modify line graphs.
4. You can manipulate axis scales for continuous data with scale_*_continuous() and scale_*_log10().
5. You can add labels to a plot such as a title, subtitle, or caption with the labs() function.
