Sankey Diagram (Cash Flow & User Funnel)
Flow diagram with smooth curved ribbons visualizing revenue distribution, cost allocations, and multi-stage funnel conversions.
◆Generating Fluid Cubic Bezier Ribbon Paths
Construct smooth multi-point SVG paths connecting source and target columns using cubic bezier control points halfway between column X coordinates.
const pathData = `M ${x1} ${y1} C ${mx} ${y1}, ${mx} ${y2}, ${x2} ${y2} L ${x2} ${y2 + h2} C ${mx} ${y2 + h2}, ${mx} ${y1 + h1}, ${x1} ${y1 + h1} Z`;◆Connecting Multi-Stage Financial Flows
Maintain double-entry accounting balance where the sum of outflow ribbons from Gross Profit equals the sum of departmental destination allocations.
A Sankey Diagram (Cash Flow & User Funnel) is ideal for developers and designers who need to display data clearly and effectively. Use this chart type when:
- ✓Building analytics overview pages with multiple metrics
- ✓SaaS product dashboards showing user activity
- ✓Business intelligence reporting screens
- ✓Admin panels with KPI summaries
What is a Sankey diagram (sankey chart react)?
A Sankey diagram is a flow visualization where the width of the connecting bands or ribbons is proportional to the quantity of flow between interconnected stages (e.g. Income to Expenses, or Marketing Channels to Paid Conversions).
How do you create a Sankey diagram in React?
In React, calculate the vertical offsets and heights for source and destination nodes, and render smooth connecting ribbons using SVG cubic bezier curves (M x1 y1 C mx y1, mx y2, x2 y2 L x2 (y2+h2) C mx (y2+h2), mx (y1+h1), x1 (y1+h1) Z) with translucent gradient fills.
Can Recharts render Sankey diagrams?
Recharts does not have a native Cartesian coordinate component for network flow graphs. However, lightweight React SVG implementations provide responsive, zero-dependency alternatives that load faster and style seamlessly with Tailwind and CSS variables.
