Turn flow data into a Sankey diagram.
Two columns — a from and a to — become flowing links sized by volume. See how customers move between stages, traffic between sources and pages, money between categories.

A Sankey diagram shows flow: links run from source nodes to target nodes, and each link's thickness is its volume. Pick the source column, the target column, and the numeric column that weights each flow (or count rows).
We detect categorical columns for the nodes and numeric columns for the flow weights.
Choose the source and target columns and, optionally, the number that sizes each flow.
Thick links are big flows. Hover any link for its exact value, then export SVG or PNG.
Tables of from/to/amount hide the movement. A Sankey makes it impossible to miss.
Every link's thickness is proportional to its value, so the dominant flows are unmistakable.
Sources and targets are ordered by total volume and capped to the top contributors for a clean diagram.
The shape shows the flow; hover any ribbon for the precise source → target value.
