Report Visuals are individual report types (e.g. bar, pie, line charts, table) which display your data in an easily consumable and interactive fashion. An App Dashboard can display one or more Report Visuals simultaneously.  

Each Report Visual has unique attributes and expected parameters.  There are several properties in the design panel that allow you to control the appearance of report visuals.

Report Tooltip Descriptions
