When to Use Sankey Diagrams
Sankey diagrams excel at showing flows, transfers, and relationships between categories. They're the go-to visualization when you need to show how quantities move from sources to destinations. Here are the most effective use cases:
Energy Flow Analysis
Visualize how energy transforms and distributes across systems. Example: Show electricity generation sources flowing to consumption sectors, or track carbon emissions through supply chains.
Budget Allocation
Display how funds flow from revenue sources to spending categories. Example: Visualize government budget distribution from tax revenue to public services and programs.
User Journey Mapping
Track how users flow through your product or website. Example: Show visitor paths from landing pages through conversion funnels to final outcomes like purchases or sign-ups.
Supply Chain Flows
Map material and product flows through manufacturing and distribution networks. Example: Trace raw materials through production stages to finished goods and end customers.
Migration Patterns
Visualize population movement between regions, countries, or categories. Example: Show talent flows between industries, customer churn between competitors, or demographic shifts.
Process Workflows
Illustrate how work items flow through business processes. Example: Map ticket routing in support systems, document approval workflows, or manufacturing process stages.
Understanding Sankey Diagram Components
Sankey diagrams consist of two main elements that work together to tell your data story:
Nodes
What they represent:
Categories, stages, or entities in your flow. Sources are on the left, destinations on the right, with intermediate nodes in between.
Visual encoding:
Node height represents total flow through that category. Colors help distinguish different categories or groups.
Customization:
Adjust width, padding, colors, and labels to match your brand and improve readability.
Links (Flows)
What they represent:
The quantity or value flowing between nodes. Each link connects a source to a target and carries a specific value.
Visual encoding:
Link width represents the magnitude of flow. Wider links mean larger quantities moving between categories.
Customization:
Control opacity, curvature, and color inheritance to create the perfect visual style for your data.
AECharts automatically calculates optimal node positions and link paths from your data. Just enter your flows and let the tool handle the layout.
