Sankey Diagram
A flow diagram showing how quantities move between stages. Supply nodes and links with values via JSON. Great for funnels, budgets, and energy flows.

When to use this template
This visualization helps to understand the distribution and magnitude of flows between different stages or categories. It effectively highlights dominant paths, bottlenecks, and where quantities diverge or converge, making it ideal for analyzing sequential processes or resource allocation.
- Categorical stages with clear sequential or parallel relationships
- Numerical values representing quantities that flow between stages
- Data where the sum of flows into a node should roughly equal the sum of flows out
- Datasets with a moderate number of distinct nodes and links for clarity
- Tracking resource allocation, material transformation, or user journeys
- Analyzing systems with inputs, intermediate processes, and outputs
