A field contains values, loaded from a data source. At a basic level, a field corresponds to a column in a table. Fields are used to create dimensions and measures in visualizations.
Selections are values selected by a user in visualizations in an app used to filter data. When a selection is made, all associated visualizations are updated to reflect the selection. Selections can be saved as bookmarks, and shared with other users.
