WPF Bubble Chart – Visualize the Relationships

Overview

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