Visualizing Data Flow: The Creative Potential of Sankey Charts

Sankey charts, named after Sankey’s diagrams, are a unique way of visualizing data flow from one place to another. They are particularly useful in understanding complex systems where data flows from one end to another and might change states, quantities, or destinations en route. These charts are not only a powerful analytical tool but also a creative visual representation that can help interpret and present complex data in an engaging and informative manner. Here we dive into the creation of Sankey charts, their applications, and the creative potential they offer.

Creating Sankey Charts

Creating a Sankey chart involves several steps, starting from data preprocessing to visualization. Here is a general process to create a Sankey chart:

  1. Collect Data: Gather data points that represent the flow between different categories. This could be in the form of numbers, quantities, or weights.

  2. Organize Data: Lay out your data in a table format with categories as columns and the points of data transfer as rows. Ensure consistency in the data formats and units.

  3. Set Up Sankey Diagram Software: Use software like Tableau, Python’s Matplotlib or Seaborn libraries, or specific software like RAWGraphs for creating Sankey diagrams. These platforms offer different tools and options for data visualization, so choose one that suits your needs.

  4. Design the Chart: Design the layout of your Sankey chart. This includes positioning the source, destination, and any intermediate nodes. Adjust the width of the flows based on the data quantity to ensure readability.

  5. Apply Color and Labels: Use contrasting colors for different data flows to highlight variations and differentiate between them. Labeling nodes and links makes the diagram more understandable and engaging.

  6. Review and Refine: Review the Sankey chart to ensure clarity, considerability, and the correct representation of data flows. Refine as necessary to make the visualization as effective and accurate as possible.

Applications of Sankey Charts

Sankey charts are versatile and have multiple applications across various fields:

  • Energy Transfers: Sankey diagrams are famously used to represent energy flows, like electricity generation and consumption, making complex processes intuitive and easy to understand.

  • Process Efficiency Evaluation: They can be used to analyze and evaluate the efficiency of processes, especially in manufacturing, agriculture, and supply chain management.

  • Ecosystem Studies: In biology, Sankey diagrams can show the transfer of materials or energy between different ecological niches.

  • Financial Flows: They are used to visualize financial flows within a company, country, or economic system.

  • Water Flow: For analyzing the flow of water from natural sources to various uses and back into the ecosystem.

  • COVID-19 Data: Sankey diagrams have been used to visualize how the virus spread across different countries, highlighting the number of cases moving from one region to another.

The Creative Potential of Sankey Charts

The creativity in a Sankey chart lies not just in the visualization but also in the narrative it conveys. With each link in a Sankey chart representing a flow, the designer can highlight specific flows or data points, leading the viewer’s attention where necessary. This flexibility allows for the creation of visually engaging and informative graphics that not only present the data but also tell a story.

Sankey charts are particularly adept at conveying complex processes and data flows, making them a popular choice for presentations, data storytelling, and educational materials. The combination of a clear visual flow with the ability to highlight important changes or anomalies makes these charts a compelling tool for both professional and educational use.

Conclusion

Sankey charts are not just about visualizing data; they are about creating a narrative that is engaging and informative. Their ability to convey complex data flows in an understandable manner makes them a powerful tool for data visualization and storytelling. Whether for academic research, business analysis, or public education, the creative potential of Sankey charts lies in their unique ability to bring complex data to life.
