Charts & Visualizations
Sankey Diagram
Sankey diagrams visualize flows (e.g., energy, materials, money, web traffic) between nodes or stages in a process. The width of the connecting bands (links) is directly proportional to the flow quantity, making it easy to see major contributions, pathways, and losses within a system.
Definition
Sankey diagrams visualize flows (e.g., energy, materials, money, web traffic) between nodes or stages in a process. The width of the connecting bands (links) is directly proportional to the flow quantity, making it easy to see major contributions, pathways, and losses within a system.
Examples
Material flow through a production process with waste and rework
Chart Visualization
This example includes an interactive chart visualization with 6 data points.
Chart type: sankey
Usage
Best Used For
- Visualizing flow quantities between stages or categories
- Showing energy balances, material flows, or cost breakdowns
- Analyzing resource allocation, website navigation paths, or process efficiency
- Tracking conversions, diversions, or losses through a system
Data Requirements
[Object]
Limitations
Important Considerations
- ⚠Can become complex and hard to follow with many nodes and crossing flows
- ⚠Layout can be sensitive to node ordering and link arrangement
- ⚠Not ideal for visualizing cyclical flows (loops)
- ⚠Reading exact flow values can be difficult; relies on proportional width
Best Used For
