What is a dashboard in Tableau?

A dashboard in Tableau is defined as a combination of multiple visualizations and content displayed on one screen. This feature allows users to see various insights simultaneously, making it easier to interpret and analyze complex data. Dashboards can include a variety of components, such as charts, graphs, maps, and text, all integrated to provide a comprehensive view of the data at a glance.

By providing an overall perspective rather than just a singular focus on one visualization or metric, dashboards enable users to identify patterns, correlations, and trends effectively. They are particularly useful in interactive analysis, where users can filter data and see the impact of their selections across all visualizations present on the dashboard.

The other options represent different, but distinct concepts in Tableau. For instance, a collection of data sources pertains to the foundational datasets being used rather than the visual representation of those datasets. A single visualization focuses on only one aspect of the data, lacking the holistic view a dashboard offers. Finally, a report designed for data summaries typically implies a more static presentation, whereas dashboards are dynamic and interactive, allowing users to engage with the data in real-time.
