## What is free

- **One funnel of up to six stages**: Bind a Stage and a Traffic measure; Stage Order sets the order, otherwise stations order by traffic.
- **Drop-offs and entries at every gap**: The line narrows as traffic leaves. Every drop-off leaves the line as an exit with its count and share; traffic that joins mid-way joins as an entry.
- **Labels at every station**: Traffic, share of start, share of previous station, or two together. Stations can be numbered.
- **Four themes, every colour, boardroom mode**: SmartVisuals, Dark, Clean and Slate, every colour yours, a per-line colour that accepts conditional formatting (fx), moving trains for wall screens and a boardroom mode that shows the same numbers as a plain table.
- **Readable at any size**: Horizontal, vertical or automatic. A small tile angles the names, then shows every other one, then drops values, before anything overlaps or is cut. A minimum text size can be set.
- **Built for real reports**: Click a station to cross-filter, click a line to filter the line, Ctrl+click for several, right-click for the context menu. Highlights from other visuals draw as a bright core inside each line. Tooltips on every station and leg, plus your own tooltip measures.
- **Accessible, in every tier**: One tab stop, arrow keys from station to station, a screen-reader table, Windows high contrast with a stripe pattern per line, and reduced motion honoured or forced.
- **No watermark, no time limit**: The free map is a finished visual. Nothing leaves your report: no network calls, no tracking, no external fonts.

## What premium adds

- **Leg times**: Bind Time From Previous Stage and every leg carries its time in days, hours, minutes, weeks or months; the end-to-end time is in the last station's tooltip.
- **Target Time (SLA)**: Legs over their target get a clock and the overrun, a dashed works-zone outline and a line in the insight sentence. Never colour alone.
- **Time heat**: Every leg coloured by its time against the median leg, from quicker to slower, no target needed. The badges keep the numbers.
- **Comparison Volume**: Last quarter, last year or plan. The change shows at every station with an arrow, the comparison width runs as a casing behind each line, and the insight names the leg whose conversion moved most.
- **The insight sentence**: How many reach the end, the biggest drop, the slowest leg, how many legs ran late and the biggest change. Computed offline in your report's number format.
- **Real processes**: More than six stages, and several lines. Bind a Line field and each value becomes a metro line; shared stages become interchanges, a branch leaves the main line and rejoins it, an express line bypasses the stations it skips.

## Fields

| Field | Internal name | Takes | Needed | What it is for |
| --- | --- | --- | --- | --- |
| Stage (Station) | `stage` | Column | Optional | The stage name. Every stage is a station; a stage that several lines share becomes an interchange. Up to 6 stages are free; more are a Premium feature. |
| Stage Order | `step` | Column | Optional | Optional number or sortable text that orders the stages. Without it, stations order by traffic, largest first. |
| Line (Path) | `line` | Column | Optional | Optional: which path a row belongs to (channel, product, route). Each value is a metro line. Several lines are a Premium feature. |
| Traffic (Volume) | `volume` | Measure | Optional | How many reached the stage: orders, candidates, tickets. Sets the line width. |
| Time From Previous Stage | `duration` | Measure | Optional | Premium: average (or median) time it took to get here from the previous station. Shown on the leg, with end-to-end time and time heat. |
| Target Time | `target` | Measure | Optional | Premium: the time a leg should take. Legs over it are flagged as late. |
| Comparison Volume | `compare` | Measure | Optional | Premium: the same traffic for a comparison period (last quarter, last year, plan). |
| Tooltips | `tooltips` | Measure | Optional, up to 8 | Extra measures shown in the tooltip. |

## Format pane
