What best describes a dashboard in Tableau?

A dashboard in Tableau is best described as a collection of visualizations displayed on a single screen. This means that dashboards are designed to present multiple types of data visualizations, such as charts, graphs, and maps, simultaneously, allowing for a comprehensive view of the data being analyzed. By bringing together various visual elements, a dashboard enables users to gain insights quickly, identify trends, and make comparisons in a more efficient manner.

The focused layout of a dashboard facilitates interactive features, such as filters and parameters, which enhance the data exploration experience. This capability to combine various data visualizations tailored to specific questions or KPIs distinguishes a dashboard from other types of data presentations.

In contrast, the other options refer to different data-related concepts that do not accurately represent what a dashboard is. For instance, a detailed report created from raw data is more aligned with a static or structured format rather than the dynamic and interactive nature of a dashboard. A spreadsheet used for data entry serves a functional purpose in managing and organizing data rather than visualizing it, and a server-side data repository refers to the storage aspect of data management rather than its presentation or visualization.
