A region is an area of land that has common features. A region can be defined by natural or artificial features. Language, government, or religion can define a region, as can forests, wildlife, or climate. A common way of referring to regions in the United States is grouping them into 5 regions according to their geographic position on the continent: the Northeast, Southwest, West, Southeast, and Midwest. Geographers who study regions may also find other physical or cultural similarities or differences between these areas.
There are many reasons to put your data on a map. Perhaps you have some location data in your data source? Or maybe you think a map could really make your data pop? Both of those are good enough reasons to create a map visualization, but it’s important to keep in mind that maps, like any other type of visualization, serve a particular purpose: they answer spatial questions.
You make a map in Tableau because you have a spatial question, and you need to use a map to understand the trends or patterns in your data.
But what is a spatial question? Some examples might be:
Which state has the most farmers markets?
Where are the regions in the U.S. with the high obesity rates?
Which metro station is the busiest for each metro line in my city?
Where did the storms move over time?
