Waterfall Chart Maker
Reconcile a starting value, ordered gains and losses, and a stated ending value before drawing the bridge.

What a waterfall chart shows
A waterfall chart shows how one number became another: a starting value on the left, an ordered run of gains and losses in the middle, and the stated ending value on the right. Each bar floats where the previous one finished, so a bar's height is a change and its position is the running total.
Finance draws the same picture and calls it a bridge — a revenue bridge, a margin bridge, a cash bridge. Built by hand, it is a stacked bar chart with the connecting segment made invisible, and that invisible segment is a formula nobody checks. Which is why waterfall charts are so often wrong in ways nobody notices.
The check is the point of this one. You state the ending value you expect; the builder adds the start and the steps and compares. If the two disagree the chart is not drawn at all — you get the gap instead, in value and in per cent, because a bridge that does not reconcile is a chart asserting a number nobody can trace.
- Start value — where the period, budget or balance began.
- Steps — one gain or loss per line as "Name, amount", in reading order. Negative amounts are losses. Twelve steps maximum.
- Stated end — the number you are claiming the steps add up to.
- Output — a badged SVG and the computed CSV, carrying each bar's amount, its start, and the running total it lands on.

How do I make a waterfall chart?
State the start, list each gain and loss on its own line as "Name, amount", and state the end you expect. Negative amounts are losses. The chart is drawn only when the start plus the steps equals the stated end; otherwise you get the gap, which is nearly always a missing line rather than a drawing problem.
What is a bridge chart?
The same chart under a finance name. A revenue, margin or cash bridge is a waterfall whose start and end are two reported figures and whose steps are the reconciling items between them.
