Streamlining Complexity: The Artful Elegance of Sankey Chart Storytelling

Introduction

Complex systems abound in the modern world, from the intricate networks of financial transactions to the vast infrastructures supporting global energy consumption. These systems are challenging to understand and communicate effectively. Sankey charts, with their distinct, elegant design, offer a compelling solution for visualizing these complex systems. By streamlining complexity, Sankey charts become a powerful tool for storytelling, breaking down complexity into digestible, captivating narratives. This article will demystify the basics of Sankey chart creation and explore their numerous applications across various fields.

What is a Sankey chart?

A Sankey chart is a type of flow diagram typically used to visualize the energy flow, material flow, or cost distribution in a process or system. It consists of arrows that represent the quantity flowing through a process at a given rate. The width of the arrows varies according to the magnitude of the movement they represent, allowing for a quick visualization of where most of a system’s energy or resources are being used or lost.

The Sankey chart’s design is intuitive: a wide arrow suggests a high flow rate, while a narrow arrow indicates a lower flow. The direction of the flow is typically from left to right, starting with the input energy or materials and ending with the waste or loss at the right end.

The Components of a Sankey chart

A Sankey chart is composed of the following elements:

  1. nodes: These are the points where energy or materials enter, exit, or transfer between different parts of the system.
  2. arrows: The directional flow of energy or materials between nodes.
  3. link widths: Represent the magnitude of the flow between the nodes.

Crafting a Sankey Chart

The process of creating a Sankey chart begins with defining the problem or the system you want to understand. Here’s a step-by-step guide to creating a Sankey chart:

  1. Identify Inputs and Outputs: Understand the system thoroughly to determine what the primary inputs (input nodes) and outputs (output nodes) are.
  2. Divide the System: Break down the system or process into its individual components or steps.
  3. Calculate Flow Rates: Measure or estimate the flow rates of the material or energy through each component.
  4. Set Up a Grid: Design your Sankey chart with a grid that can accommodate the various nodes and arrows.
  5. Create the Nodes and Arrows: Plot the nodes and the arrows, making sure the widths of the arrows reflect the flow rates accurately.
  6. Adjust and Refine: Review the chart and make adjustments as needed to represent the flow as you want to emphasize it.

Applications in different fields

Sankey charts have been applied in a range of sectors due to their ability to elegantly represent complex flows and relationships:

  1. Energy and Resources: For analyzing energy systems, such as how electricity is produced from different sources and how it is lost during transmission.
  2. Supply Chains: To visualize the movement of materials through the supply chain and identify inefficiencies.
  3. Business and Finance: To demonstrate financial flows, investments, or the distribution of costs across projects or departments.
  4. Environmental Science: To understand the flow of nutrients, pollutants, or carbon through ecosystems and human-made systems.
  5. Public Health: To study the transmission of diseases, population demographics, or healthcare resource allocation.

The Artful Elegance of Simplification

The beauty of the Sankey chart lies in its ability to simplify complex data and concepts. Unlike more traditional charts that pack a substantial amount of information and could be overwhelming, Sankey charts filter out the noise and allow the viewer to focus on the most significant attributes of the system being visualized.

By embracing the art of simplification, Sankey charts transform intricate patterns into a narrative that everyone can follow. Whether you’re a data analyst, a policymaker, or a student, the ability to tell a compelling story through a Sankey chart can have meaningful implications—a single, clean chart can change the way people perceive and interact with complex systems.

Conclusion

Streamlining complexity is a fundamental challenge in the analytics toolkit, and Sankey charts stand out as a beacon of artful elegance in the sea of data visualization methods. With their unique ability to tell a story through the flow of energy, material, and resources, Sankey charts offer a valuable and accessible way for professionals and laypeople alike to engage with complex systems. As the quest to understand and manage complexity continues, the Sankey chart will undoubtedly remain a beloved instrument in the data analyst’s toolbox, enabling a greater capacity to communicate efficiently and effectively.
