Streamlining Insights: A Splash of Color in Sankey Chart Storytelling

Introduction

In data visualization, the use of powerful and intuitive tools to convey complex relationships is paramount. Sankey charts, a form of flow diagram, are making waves in this realm due to their unique ability to depict how energy, materials, or information flows through a process. By harnessing the beauty and depth of color, Sankey charts become more than just another data visualization tool; they become powerful narratives that guide viewers through the story of a system’s flow.

In this article, we delve into the intricate process of creating Sankey charts and explore their diverse applications in various fields, underscoring how adding a splash of color can enhance story-driven storytelling.

Understanding Sankey Charts

Sankey charts, invented by 19th-century engineer WilliamPlayfair, are specialized diagrams used to illustrate material, energy, or cost streams through a process. They feature arrows that are drawn to a consistent width to represent the quantity of flow passing through each link of the process, with the width proportionally corresponding to the quantity of the flow.

The strength of Sankey charts lies in their visual fidelity to the process flow; they reveal the most significant connections and inefficiencies at a glance. Each Sankey chart consists of nodes—points where processes interact—and links—arrows indicating flow within the process. The challenge in creating a Sankey chart lies in maintaining the balance between realism and readability.

Creation Process: A Colorful Conundrum

Creating a Sankey chart requires attention to detail and a methodical approach. Here are the steps involved in designing an effective Sankey chart:

  1. Identify the Process: Begin by defining the process or system you want to visualize. Identify all the inputs, outputs, and transformations involved.

  2. Collect the Data: Gather flow quantification data for each stage of the process. Ensure that the data is normalized to the same scale to make meaningful comparisons.

  3. Choose Your Tools: Select a Sankey chart tool that suits your requirements. There are many free and paid tools available, including SankeyJS and Gephi, which offer extensive customization options.

  4. Design the Layout: Lay out the chart with nodes connected by links. Utilize the available tools to adjust the arrow widths to reflect the relative flow values.

  5. Color Coding: Color is a powerful tool for storytelling in Sankey charts. Use distinct colors to represent different parts of the process, making sure to avoid excessive color coding that might overwhelm the viewer.

  6. Layering and Clarity: Group related elements together to enhance clarity without sacrificing detailed insights. Use transparency to resolve instances of overlapping arrows or nodes.

  7. Review and Adjust: Continually refine your chart by reviewing it against the intended message or purpose. Pay attention to readability, and ensure the chart tells an accurate story about the process.

Applications of Sankey Charts

Sankey charts are adaptable and versatile tools, with applications spanning multiple industries:

  1. Energy Industry: Visualizing energy usage, loss, and conversions in power plants or renewable energy systems.
  2. Supply Chains: Demonstrating the flow of goods, materials, or money within a supply chain.
  3. Data Flows: Illustrating the movement of data within an organization or between different systems.
  4. Economic Modeling: Analyzing the flow of resources, production, and consumption within an economic system.
  5. Environmental Monitoring: Tracking the flow of greenhouse gases, pollutants, or other environmental factors.

Conclusion

In storytelling through data visualization, color plays a crucial role in highlighting key information and guiding the viewer’s understanding. Sankey charts offer a compelling mode of representation, using the dynamics of flow and the richness of color to convey insights effectively. By mastering the creation process and applying it thoughtfully, data storytellers can craft narratives with Sankey charts that are both informative and visually engaging—the perfect splash of color for the data-driven world.
