A Set is a feature where you can gather collections of data for a discrete purpose - be it an analytics project, a reading list, or a way to organize your data spatially.
You can view all the sets in your instance by clicking the "Sets" header in the left hand navigation menu:
You can also view a single set by selecting the specific set you are interested in, in the same left hand navigation menu.
You can create a set by clicking the "+" icon on the Sets menu option:
You can delete sets by clicking the checkbox next to their name, clicking the "Selected" button in the top right, and "Delete".
Example Uses for Sets
