# Funnel chart A React component in [Beamline](https://beamline.io/)'s [Charts & data-vis](https://beamline.io/components/charts) category. Live demo: https://beamline.io/components/funnel-chart People or deals moving through ordered steps, each step a bar narrowing from the first: the part lost between two steps stays beside the next as a fading ghost with its count, the step's conversion and the conversion from the start read between them, a previous period shows as a mark on each bar with its change, and a step never measured is hatched rather than read as zero. ## Use it for - A sequence where each step keeps part of the one before: visit → signup → activation → paid, lead → deal → won, cart → checkout → order. - Finding the step that loses the most, and whether it got better against last period. ## Not for - Flows that branch or merge between stages ([sankey-chart](https://beamline.io/components/sankey-chart)). - Independent categories without an order ([bar-chart](https://beamline.io/components/bar-chart) or [bar-list](https://beamline.io/components/bar-list)). - Shares of one whole ([pie-chart](https://beamline.io/components/pie-chart) or [waffle-chart](https://beamline.io/components/waffle-chart)). ## Anatomy - chart frame: title, description, table button (every step with value, step conversion, from start and previous) - step row: name, value, the bar (centred, or from the start edge), the previous period's mark and change - between steps: the step's conversion and the count lost, with the lost part kept as a ghost beside the next bar - footer: conversion from the first step to the last ## Variants - **0**: shape: centred (a funnel) · aligned (bars from the start edge, easier to compare lengths) - **1**: previous: the same steps last period (marks and ▲ ▼ change) - **2**: format and percent format ## States - loading (bars of falling width waiting) - empty - not measured (a null step: hatched, its conversions read “not measured”) - active step (hover, focus or pinned: others fade toward the card, its numbers lead) - data changed (bars glide to their new widths, the lost parts drain) - table view - Loss and ghost width use the immediately previous measured step; an unknown boundary has no numeric loss or drop-off ghost. ## Keyboard - Tab reaches the steps as one list; ↑ ↓ move between steps, Enter pins one, Escape unpins - The table view carries every number for a screen reader ## Motion Bars grow from the centre (or the start edge) in turn on first draw. New data glides every bar to its width over the chart duration; a step that loses people keeps the lost part as a ghost that drains, a step that gains arrives lit (the shared delta grammar). Pointing fades the other steps at once. Reduced motion shows the result at once; nothing runs at rest. ## Props | Prop | Type | Default | Description | | --- | --- | --- | --- | | `steps` (required) | `FunnelStep[]` | — | { key, label, value: number \| null } in order. | | `previous` | `(number \| null)[]` | — | The same steps last period, in the same order. | | `previousLabel` | `string` | — | What the previous period is called. Default "Previous period". | | `shape` | `"centred" \| "aligned"` | — | Default centred. | | `format` | `(value: number) => string` | — | How counts read. | | `percent` | `(share: number) => string` | — | How conversions read; share is 0–1. Default one decimal. | | `active / defaultActive / onActiveChange` | `string \| null` | — | The pinned step's key. | | `title / hideTitle / description / table / loading / emptyLabel / actions` | `…` | — | The chart frame every chart shares. | | `className / classNames / style / ref` | `string / ChartClassNames / CSSProperties / Ref` | — | The chart figure and its frame parts. | ## Dependencies `motion` ## Import ```tsx import { FunnelChart } from "@/components/funnel-chart/funnel-chart"; ``` ## Get it Funnel chart is part of Beamline: 200+ components and 50+ complete screens for React that your coding agent (Claude Code, Codex, Cursor or any MCP client) installs into your app through Beamline's MCP server, as a ready-built package or as plain React source you can change. $49 launch price, one payment, no subscription, lifetime updates, one licence for your whole team.
