WinUI Bubble Chart – Visualize the Relationships

Overview

The WinUI Bubble Chart visualizes data in three dimensions and it looks similar to scatter charts. The position of a circle is determined by X and Y values, and the radius of a circle is based on the size value. The chart supports zooming, scrolling, tooltip, trackball, and selection.
