Overview

The .NET MAUI bubble chart visualizes data in three dimensions similar to a scatter chart. A data point’s position is determined based on x- and y-values and the radius of its circle is determined by a size value. You can create beautiful, animated, real-time and high-performance bubble charts that also support interactive features such as zooming and panning, trackball, tooltip, and selection.
