Understanding Sankey Diagrams
What is a Sankey Diagram?
A Sankey diagram is a flow diagram where the width of the arrows or links is proportional to the flow quantity. These diagrams are particularly useful for visualizing the transfer of energy, materials, costs, or any other type of flow between processes or stages.
When to Use Sankey Diagrams
- Visualizing flow processes and transfers
- Analyzing energy or material flows in systems
- Tracking conversion or loss in processes
- Displaying budget flows or resource allocation
- Showing customer journey or user flow analysis
Best Practices
- Keep the number of nodes manageable for clarity
- Use meaningful colors to group related flows
- Arrange nodes to minimize link crossings
- Include clear labels and values where appropriate
- Consider the orientation based on your data flow
