What its author says it does

Copied from the file, not written here

Render a conversion funnel with stage bars whose widths are proportional to count, drop-off annotations between stages, and a final accented bar for the terminal stage. Use for acquisition / activation funnels, feature adoption funnels, and search-result click-through analysis.

paperchart — funnel

Stages stack vertically. Bar width is proportional to count. The last stage gets the accent. To the right of each subsequent stage, the renderer shows survival rate and absolute loss vs. the previous stage.

When to use

Acquisition funnels (visit → signup → activation → retention).
Feature funnels (search opened → query submitted → result clicked → page consumed).
Any multi-step conversion narrative.
