How can users drill down into data visualizations in Power BI?

Users can drill down into data visualizations in Power BI primarily by enabling drill-down features. This functionality allows users to interactively explore data hierarchies within a visual. For instance, if a user is viewing sales data by year, they can drill down to see sales by quarter, then by month, and so on. This interactive capability is crucial for detailed data analysis, providing insights into underlying data without having to create multiple visuals or reports.

The ability to drill down enhances the analytical experience by allowing users to start with a high-level overview and then progressively uncover deeper insights. With drill-down features enabled, users can click on specific elements within a visual to navigate through the data layers, fostering a more dynamic understanding of the information being displayed.
