A Funnel Series illustrates how a value changes during a process, with a line representing the value at each stage and filled areas denoting the change between them.
 Simple Cone Funnel Copy Link  
To create a Cone Funnel Series, use the cone-funnel series type.
{
    series: [
        {
            type: 'cone-funnel',
            stageKey: 'group',
            valueKey: 'value',
        },
    ],
}
In this configuration:
stageKeydefines the stages which are used for the lines of the cone funnel.valueKeyprovides the numerical values which determine the width of line.
 Horizontal Cone Funnel Copy Link  
To create a horizontal Cone Funnel Series, set the direction to horizontal.
{
    direction: 'horizontal',
}
 Customisation Copy Link  
{
    fills: ['#5090DC', '#FFA03A', '#459D55'],
}
In this configuration:
- The fills for each drop off area are defined in the 
fillsarray. - The Cone Funnel series is reversed by providing the data items in the reverse order.
