WPF Funnel Chart - Visualize Data Easily

Overview

The WPF Funnel Chart is like a pyramid with two parts. The higher part is called the head, and the lower part is called the neck. The funnel chart is often used to represent stages in a sales process and to show the amount of potential revenue for each stage. It makes proportional comparisons between values that are showcased as progressively decreasing. The segments in the WPF Funnel Chart can be exploded and differentiated using different colors. It supports zooming, scrolling, tooltip, trackball, and selection.
