How to create report page tooltips in Power BI Desktop

The core principle involves a mechanism for triggering dynamic context-aware data visualization overlays upon user interaction within business intelligence environments. This concept relies on explicit field mapping between the base visual element and the overlay page to override default automated attribute detection, ensuring that tooltips render only when specific hierarchical or categorical attributes exist at the current filter context. The theory operates within the domain of interactive dashboard design and belongs to the broader discipline of data visualization, where it serves as an advanced interaction pattern for granular information delivery beyond static labels.
