Note: the latest version of {ggplot2} has added an aesthetic called `linewidth` that will replace `size` aesthetic for scaling the width of lines in line based geoms like `geom_line()`. The `size` aesthetic will still work, but it is recommended to update all code to reflect the new aesthetic.

Unfortunately, our lesson was written and recorded before release of the update.  We have updated this quiz and lesson notes, however the lesson video has not been edited yet. Apologies for any inconvenience.
