What mode in dashboard authoring allows you to design the dashboard?

The correct choice is Design Mode. This mode is specifically tailored for users who are creating and structuring the content and layout of a dashboard. Design Mode offers a comprehensive set of tools and functionalities that facilitate the arrangement of various elements, such as graphs, charts, tables, and other visualization components, allowing for a customized and visually appealing dashboard that meets specific user requirements and expectations.

In Design Mode, users can manipulate the components to ensure that the layout is logical and that the data conveyed is clear and insightful. It enables users to drag and drop features, adjust settings, and configure properties of the dashboard elements, providing full control over the design process. Understanding this mode is crucial for creating effective dashboards that align with the intended audience's needs.

The other options do not serve the same purpose as Design Mode. Preview Mode typically allows users to view the dashboard as it will appear to end users without making changes. Edit Mode might suggest making adjustments but lacks the focused tools specifically for designing dashboards. Test Mode usually pertains to validating functionalities or data accuracy rather than the design element of the dashboard. Therefore, Design Mode is the appropriate choice for the task of dashboard authoring.
