Learning Objectives

By the end of this chapter, you will be able to:

Use choropleth maps to represent data across geographical regions
Generate interactive choropleth maps, including choropleth maps depicting countries in the world and maps depicting states in the US, making layout changes to add functionality/aesthetic appeal, and adding animation
Generate interactive scatter plots on maps, including scatter plots indicating geolocations of places of interest and interactive bubble plots on maps
Generate interactive line plots on maps, including line plots indicating trajectories on a map

In this chapter, we'll learn about using interactive visualizations to depict data across geographical ...
