What is a Dashboard in Tableau?

A dashboard is a collection of several views, letting you compare a variety of data simultaneously. For example, if you have a set of views that you review every day, you can create a dashboard that displays all the views at once, rather than navigating to separate worksheets.

It allows users to get a holistic view of all the data on one screen. Creating dashboards is just about dragging views from the sheets section to the visualization area.
