In this chapter, you learned the common types of map that are created and when to choose and what type to use when creating your own map. Understanding the purpose of your map and the audience is key to making the best map for the job. You also learned how you can use cartographic license to generalize data to make your map clearer without taking away from the accuracy of your map and when it is okay to leave out labels. Understanding when you can take a hit in accuracy to make your map easier to understand will help create better maps. Finally, you learned how to properly aggregate data and what common methods you can employ to make large amounts of dense data easier to perceive.
In the next chapter, you will learn about coordinate systems, projections, how to take something that is 3D and put it on a 2D surface, and how important coordinate systems and projections are for keeping your data and analysis accurate.
