Sankey diagram

Weighted flow diagram with nodes and links — node height equals flow.

Basic usage

Data is passed via props and rendered as pure SVG, with no third-party charting dependency. Colors are drawn from the --viz-1..8 tokens and are colorblind-friendly.

Node drag

draggable defaults to true. Press and drag any node vertically to manually reorder its layer; links update in real time. Subscribe to @node-drag / onNodeDrag for the drop-position delta. Set draggable={false} for a read-only view.

竖直拖拽 → 自动按落点 y 重排同层顺序;横向拖到另一列附近 → 节点跨层迁移,源层 / 目标层同时收紧。
