Funnel chart
Funnel charts are often used to represent stages in a sales process and show the amount of potential revenue for each stage. By default, the height of a slice represents it’s value. However you might want the area of a slice to represent value. In this case you should add "valueRepresents":"area" property to the chart’s config. The height and width of a neck is controlled by neckWidth and neckHeight properties.
