Unleashing the Power of Flow: A Visual Journey with Sankey Charts
Sankey charts, also commonly known as Sankey diagrams, are powerful and visually stunning tools for visually representing flows and the distribution of quantities from one set of values to another. Originating from the work of Matthew Holdway and Charles Richard Sankey in the late 19th century, they have gained immense popularity over the years for their unique aesthetic and ability to convey information in a comprehensive and intuitive way.
What are Sankey Charts?
Sankey charts are a type of flow diagram wherein the flow between quantities is visualized as arrows crossing through a plane with marked nodes. These diagrams are particularly useful for displaying the energy consumption breakdown, financial flow, material distribution, data flow, traffic flow, and information transmission, among many other applications.
Key Elements of a Sankey Chart
Nodes
Each node in a Sankey chart represents a specific quantity or category, showing the origin and/or destination of the flows.
Links
Links or arrows visually connect the nodes, emphasizing the quantity of flow between specific categories. The width of the links corresponds to the value being transferred.
Flows
The flows between nodes can be color-coded to make tracking and understanding the source and destination of material flow easier and more intuitive.
Creation and Applications of Sankey Charts
Creating Sankey Charts
Creating a Sankey chart involves several steps:
1. Data Collection: Gather all the necessary data related to the flows you wish to represent.
2. Choosing a Tool: Use software tools like Microsoft Excel, Tableau, or specialized Sankey chart creation software like Canva or KoolChart.
3. Inputting Data: Input the gathered data into the chosen tool, specifying nodes, flows, and quantities.
4. Designing the Chart: Adjust the layout, colors, and other design aspects to ensure clarity and visual appeal.
5. Review and Adjust: Review the chart for accuracy and clarity, making adjustments as necessary to enhance comprehensibility.
