When to use a Sankey Diagram
- Showing how quantities flow through a multi-stage process
- User journey and funnel analysis with multiple paths
- Energy, material, or budget flow between categories
- Visualizing source-destination flows (imports/exports, traffic sources)
About the Sankey Diagram
A Sankey diagram shows flows between a set of nodes. The width of each flow link is proportional to the quantity flowing between the connected nodes. Nodes are typically laid out left-to-right, representing stages in a process or a breakdown of categories.
Sankey diagrams are ideal for energy flow, budget allocation, user journey analysis, and material flow studies. They quickly reveal where the biggest flows are and where losses or conversions happen.
