Which feature provides a fixed and read-only design for rapid dashboard creation?

The feature that provides a fixed and read-only design for rapid dashboard creation is the layout templates. Layout templates allow users to quickly create dashboards by providing predefined arrangements of components and visualizations. These templates ensure a consistent look and feel across dashboards while enabling users to focus on populating the dashboard with relevant data rather than spending time on the design aspect.

Using layout templates streamlines the dashboard creation process significantly, as users can select a template that best fits their needs and then proceed to fill it in with the necessary data and visualizations. This approach is particularly useful for teams that require rapid deployment of dashboards to share insights without getting bogged down in customization or design details.

In contrast, the other options do not primarily focus on fixed, templated designs meant for rapid deployment. Manual templates are more about custom structures that require user intervention, interactive filters enable dynamic user engagement with data but don't determine the layout or design, and custom reports usually require more granular setup and modification compared to layout templates.
