What is the primary function of tooltips in Power BI reports?

The primary function of tooltips in Power BI reports is to provide additional context and information when hovering over visuals. Tooltips enhance user interaction by showing more detailed data points that may not be directly visible on the report. This allows users to gain insights without cluttering the visual with excessive information. For instance, when a user hovers over a data point in a chart, the tooltip can reveal specific values, labels, and descriptive statistics that help in understanding the data better.

This feature enriches the user's experience, as it enables an efficient way to convey complex information while keeping the visuals clean and focused. The interactive nature of tooltips makes it easier for report consumers to explore data and gain deeper insights directly within the visual context.
