Profiling is conceptually different from the other types of questions. It means applying a splitting technique by which you create a chart and then generate multiple versions of this chart, one for each category in a splitting variable. For example, you can create a population pyramid for the entire country and then generate multiple pyramids, one per region.
Profiling allows you to quickly evaluate dozen of entities, comparing them to the overall profile or detect abnormal behavior.
Charts are displayed on a grid, ordered by some meaningful variable. You can also place them in a way that has a geographical meaning (tilemaps).
