SfFunnelChart class

Renders the funnel chart.

A funnel chart is a specialized chart type that demonstrates the flow of users through a business or sales process. The chart begins with a broad head and ends in a narrow neck.

The number of users at each stage of the process are indicated from the funnel's width as it narrows.

To render a funnel chart, create an instance of FunnelSeries, and add it to the series property of SfFunnelChart.
