A funnel chart displays values as progressively decreasing proportions.
FunnelChart: (props: IFunnelChartProps) => JSX.Element
You can define funnel chart using either multiple measures or single measure and a viewBy attribute whose values will be used to slice the single measure.
In either case, the measure values will be charted into a funnel. With the largest values being on the broadest part of the funnel, and the smallest values towards the narrow part of the funnel.
See IFunnelChartProps to learn how to configure the FunnelChart.
