Exploring map options

“

- [Instructor] The world is a globe shaped object in three dimensional space. However, like most models, we can flatten the dimensions to a two dimensional plane. Wherever in the world we're standing right now we have exact latitude and longitude coordinates for our location. I'm in Carpinteria, California right now recording this course, you can see my exact latitude and longitude coordinates, but the city of Carpinteria is bigger than this so this is an exact location, but we can use latitude and longitude coordinates to create geographical shapes. We can find geographical shapes for the world, country, US states, and so on. Let's first make the US state and county fields geographical data categories within our Power BI model. (mouse clicking) Now let's visualize our US state populations in a few ways. Let's create an Azure Map visual first with the states' locations. To use Maps in Power BI make sure to first enable them in your tenant settings. The locations we see on the map approximate the center of each state. And the map will use the most recent population as the size. We can change the circle colors through the Bubble layer color options as well. (mouse clicking) We can see that California has the largest bubble size because it has the biggest population. If we zoom into the map, we can see the exact location of Carpinteria. (mouse clicking) We can also represent states using a filled map where we'll use color instead of bubble size to represent magnitude. (mouse clicking) We'll put the state and location, and the most recent population in color. (mouse clicking) So we can then specify the color for the map by going to Layer options. (mouse clicking) I'm not a huge fan of this default color scheme, so we can change it within the same Layer options. (mouse clicking) Maps aren't often very useful in Power BI by themselves, but in tandem with other visuals on a page, or within a report they can have quite an impact. Map visuals are an impactful way to communicate geographical trends.
