Possible questions to reflect on
Remember, you don’t need to answer all of these—or even any of them! These are just here to help guide your thinking. Write about whatever you want.
- How can you know if a map projection is truthful or misleading?
- What’s wrong (or not wrong) with using points on maps? Choropleths? Lines?

Check out this post where someone used {ggplot2} and {sf} to create fancy city map-based art that she printed for a friend. You can do similar things after this session!
In addition to the example for this session, you can check out this tutorial on using the {sf} package to create maps. It shows how to include fancy map stuff like a north arrow and scale bar.
