Sankey charts are a fascinating and visually stunning type of data visualization that can help us understand the flow of data, energy, or resources through a complex system. Named after the Scottish engineer Matthew Henry Phineas Riall Sankey, who popularized their use in the 19th century, Sankey diagrams have since found a wide range of applications in fields as diverse as economics, engineering, and environmental science. The key strength of Sankey charts lies in their ability to simplify complex flow patterns and reveal insights that might be obscured in lesser forms of data visualization. In this article, we’ll explore the world of Sankey charts, from basic principles to advanced techniques and real-world applications, all wrapped up in the exciting world of Flow Fantastic.

Basics of Sankey Charts

At their core, Sankey diagrams are a type of flow chart that uses wide and narrow bands, or “arrows,” to represent the flow intensity. The width of each band corresponds to the volume, quantity, or energy of the flow, making it easy to compare flows visually. This characteristic makes Sankey charts particularly well-suited for situations where the magnitude of flow between different elements is a critical piece of information.

Key Components of a Sankey Chart

• Nodes: These are the main areas or categories in the diagram. Nodes can represent sources, sinks, producers, or consumers of the flow.
• Links or Arrows: These represent the flow or movement between nodes. The width of the links visually encodes the magnitude of the flow.
• Labels: These provide information about the flow’s characteristics, such as the type of data being transferred or the volume of flow.

Creating Sankey Charts

Creating a Sankey chart typically involves several steps:

1. Data Preparation: Start with a dataset that includes information about flows between different categories. This data might come from a variety of sources, like financial transactions, energy consumption, or material flows.

2. Data Aggregation: Depending on the complexity of the data, you may need to aggregate data points into meaningful nodes or categories to represent the system’s structure.

3. Creating the Chart: Use data visualization software or libraries like D3.js, Tableau, or Matplotlib to create the chart. You will input your data and apply a Sankey chart builder tool within the software.

4. Customization: Enhance the readability and aesthetics of the chart by adjusting the color scheme, labels, layout, and other visual elements.

Applications of Sankey Diagrams

Sankey charts find applications across various fields:

• Resource Management: Visualizing energy consumption or waste flows in industries and municipalities.
• Economic Analysis: Mapping trade flows between countries to analyze economic relationships.
• Ecosystem Analysis: Tracking nutrient or species migration in ecological studies.
• Data Flow Diagrams: Representing how data moves through computer systems.
• Population Studies: Showing migration patterns within a country or between countries.
