Creating maps

Representing geospatial data on a map is surprisingly simple in Metabase. Most of the time, it "just works." To see what I mean, let's try a quick example.

Creating a region map of users by US state

Let's look at the steps to create a region map of users by US state:

1. Click Ask a Question.
2. Click Custom question.
3. In the Data section, choose Pies and Users.
4. In Summarize, choose Count of Rows.
5. In the Grouping section, choose State.
6. Click Visualize.

This will return an attractive map of the US filled in with a blue gradient mapped to display the count of users in each state, just as in Figure 7.17. We can see that most of our users are in California, which makes sense because that is where we are headquartered! It's also the most populous state in the US. However, our plot shows that almost 4 times as many users are in California compared to Texas. We can see Wikipedia that California only has about 37% larger...
