Syncfusion React Sankey

Syncfusion's React Sankey component is purpose-built for visualizing flows between nodes, whether that's energy consumption, process dependencies, or data movement through systems. It comes with the full Syncfusion feature set: tooltips, legends, RTL support, export to images, and WCAG accessibility baked in. The API uses declarative node and link directives, which feels natural in React but does require injecting services like SankeyTooltip and SankeyLegend explicitly. Link styling options like opacity, curvature, and color inheritance from source nodes give you control over appearance. If you need a production-ready Sankey diagram without building one from scratch with D3, this handles the details.
