Sankey Diagram Maker

Use Sankey for flows between stages or systems, keep labels concise, avoid unreadably dense networks, and verify the final SVG before publishing.

Use Sankey diagrams for flows

Each row is a source, target and non-negative flow value. Link width represents magnitude, so use consistent units and avoid mixing counts, money and percentages in one diagram.

Dense networks need simplification

Too many nodes or tiny flows can make a Sankey diagram unreadable. Aggregate low-value paths or switch to a table when precise comparison matters more than flow structure.
