Why it matters

When to use a sankey diagram

Showing how a measurable quantity flows between stages, categories, accounts, channels, or destinations when the width of each connection represents its value.

Avoid a Sankey diagram when the data does not describe a real flow, when values cannot reconcile across stages, or when too many small links make the paths impossible to follow.

Capabilities

What you can do with Sankey Diagram Maker

Purpose-fit chart selection

The AI can aggregate repeated source-target pairs, order nodes by stage, size links proportionally, limit minor paths, and flag flows that do not reconcile with the stated totals.

Explicit data mapping

At minimum, provide a source field, target field, and non-negative numeric value for each connection. Multi-stage flows should use consistent node labels and reconciliation rules.

Aggregation you can review

Specify sums, averages, counts, rates, time intervals, and filters so the values behind the visual remain inspectable.

Editable reporting output

Refine titles, labels, colors, annotations, and chart type, then reuse the visual in a dashboard or report.

How it works

Go from source data to a useful result in three steps

  1. 1

    Upload or paste the data

    Start with Excel, CSV, or a table and confirm that headers, numeric values, categories, and dates were interpreted correctly.

  2. 2

    Describe the comparison

    At minimum, provide a source field, target field, and non-negative numeric value for each connection. Multi-stage flows should use consistent node labels and reconciliation rules. Explain the audience and the question the chart should answer.

  3. 3

    Validate and refine the chart

    Check the values, labels, scale, and filters. Avoid a Sankey diagram when the data does not describe a real flow, when values cannot reconcile across stages, or when too many small links make the paths impossible to follow.
