Circular Sankey Diagram

Circular Sankey extends flow analysis to cyclic systems. Unlike standard Sankey charts, it can display feedback loops and return paths, which makes it useful for recirculating processes and iterative journeys.

Use Circular Sankey for revisit behaviour, closed-loop operations and systems where output can become input again. It keeps flow magnitude readable while preserving cyclical logic.

Key features

• Link colouring modes include circular vs non-circular, input-output gradient, input only and output only.

• Control readability with inside/outside label position and node/link label colour settings.
• Fine-tune appearance with node/link opacity, node borders and dedicated circular/link colours.
• Optional hide nulls behaviour for cleaner flow paths.
• Separate tooltip and label templates for nodes, from-links and to-links.
