Groups, Sets, and Hierarchies are three of Tableau's most powerful organizational features — and most analysts under-use all three. Groups let you bundle dimension members into custom categories. Sets let you create dynamic in/out segments that respond to user interaction. Hierarchies let you drill from continent → country → city with a single click. Together, they unlock a whole new level of analytical flexibility.
