What feature would be most useful for navigating to detailed reports when selecting a category in a dashboard?

The most useful feature for navigating to detailed reports when selecting a category in a dashboard is the drillthrough functionality. Drillthrough allows users to click on a certain data point or category within a visualization and then seamlessly navigate to a more detailed report that provides in-depth insights related to the selected data.

This feature enhances user interactivity and offers a focused view on specific aspects of the data, making it ideal for exploring underlying details or additional context surrounding a particular category. It effectively takes users from summary-level information to granular-level analysis, which is particularly valuable when detailed exploration of certain data segments is required.

In contrast, other options such as drill-down, cross-highlighting, and cross-filtering serve different purposes. For instance, drill-down allows users to explore hierarchical structures within data visualizations but does not necessarily redirect them to a different report or page. Cross-highlighting and cross-filtering facilitate interactivity within the same dashboard view but do not provide the same level of detail as drillthrough does by transitioning to a separate report. Therefore, for the purpose of moving to detailed reports based on a category selection, drillthrough is the most appropriate choice.
