Showcase diminishing values with this single series chart that displays data in a funnel shape. A variable number of sections represent the data as different portions of 100%. End users can easily illustrate value "fallout" in the sales process or bottlenecks in the flow of a multi-step process.
Create a notification when a slice in the funnel is clicked to highlight that it's been selected.
Inverted and Arc Funnel
Invert the funnel to display it as a pyramid, or make the funnel sides curve in or out on a Bezier curve.
