Dashboard definition
From a Tableau perspective, a dashboard is an arrangement of individual visualizations, along with other components such as legends, filters, parameters, text, containers, images, extensions, buttons, and web objects that are arranged on a single canvas. Ideally, the visualizations and components should work together to tell a complete and compelling data story. Dashboards are usually (but not always) interactive.
