Funnel · Reversed funnel

Reverse the silhouette without reordering stages.

Use a funnel for a small ordered sequence. Row heights are proportional to values, not polygon areas. Percentages are shares of the visible-stage sum, never conversion or retention against the first stage.

Supply 1–16 stages with unique stable IDs, labels and finite nonnegative values. Null is rejected. Source order stays stable. Zero remains navigable without a painted or touch polygon; hiding stages reflows the remaining heights.

Configure the neck width and height in options.layout, each from 0 to 1; defaults are 0.3 and 0.25. reversed defaults to false. Stage colours, legend, labels, individual detail and pinning are available. No axes, viewport, stacking, shared tooltip, markers, crosshair or point overrides.
