What does drill-down behavior allow users to do in Power BI?

Drill-down behavior in Power BI enables users to explore detailed data through visual interaction. This functionality is a key feature of data visualization tools, allowing users to navigate from aggregated or summary information down to more granular data. For example, when analyzing sales data, a user can start at a high-level view showing total sales by region and then "drill down" to see the breakdown of sales by individual stores or products within that region.

This capability enhances the user experience by providing insights at different levels of granularity, facilitating a deeper understanding of the underlying patterns and trends in the data. Users can interact with the visualizations by clicking on data points to reveal more detailed views, making it easier to conduct in-depth analysis and derive actionable insights.

In contrast, viewing more summarized data would not utilize the drill-down function, changing visual styles pertains to the aesthetic adjustment of the visualizations, and implementing model relationships refers to the underpinnings of data modeling rather than user interaction with visual elements.
