The River of Data Flows: Unveiling the Stories Told by Sankey Charts

In an era where data is the new oil, the ability to visualize complex, dynamic systems and identify patterns is more crucial than ever. This is especially true when examining complex relationships and flows across multiple variables. One such innovative tool that has become increasingly popular in recent years is the Sankey chart. These unique graphical representations reveal the intricate tapestry of flows within a system, allowing us to understand the stories told by the river of data.

What is a Sankey Chart?

First developed in the 19th century to represent energy flow in thermal engines by the German engineer, Karl Ernst von Siemens, the Sankey chart has evolved over time. A Sankey chart, also known as a Sankey diagram, is a directional flow diagram where the width of the arrows represents the quantity of flow transmitted by the arrow. Sankeys are used to depict the energy or material flows in a system, particularly in processes and supply chains.

Sankey Chart Creation

Crafting a Sankey chart involves defining the flow elements and the processes that the chart represents. Here are the primary steps in creating a Sankey chart:

  1. Identify the System: Determine the system or process for which the flow diagram is needed. This could range from a manufacturing supply chain to the energy transfers in an ecosystem.

  2. Break Down the Process: Analyze the system to determine how energy or material moves through it. Break the process into smaller steps or segments.

  3. Assign Flow Variables: Decide on the variables you want to use. These could be mass, energy, cost, or time.

  4. Calculate the Flow Quantities: Measure or estimate the flow quantities, such as inputs, outputs, and conversions in the process.

  5. Design the Chart Layout: Begin designing your Sankey chart layout, deciding on the direction of the flow (usually from left to right or top to bottom) and the placement of the flow segments and process steps.

  6. Plot the Sankey Chart: Using specialized software or applications like Microsoft PowerPoint, Visio, or dedicated software like Sankey Software or Gephi, create your chart. The width of each segment is directly proportional to the amount of flow it represents.

  7. Label and Detail: Label each segment clearly and include annotations or detailed descriptions if necessary to enhance understanding.

Sankey Chart Applications

Sankey diagrams are versatile and have an array of applications across various fields:

  1. Energy Analysis: Sankeys are ideal for illustrating energy flows in power plants, buildings, or entire economies, highlighting energy losses and inefficiencies.

  2. Environmental Studies: Sankeys can demonstrate the movement of pollutants, water flow in ecosystems, or even the carbon footprint of cities and industries.

  3. Economic Analysis: They can illustrate how goods or services are produced, processed, and consumed, providing insights into economic interactions.

  4. Transportation Planning: Sankeys are useful to visualize traffic flows, evaluating the effectiveness of traffic management systems and planning more efficient routes and infrastructure.

  5. Supply Chain Management: They help in depicting complex supply chain networks, identifying bottlenecks, and optimizing the flow of materials and products.

The Stories Told by the River of Data

Sankey charts allow us to see the often invisible flows of data in a way that is visually intuitive. At a glance, they tell the story of how energy or resources are transformed and distributed within a system. For instance, if a Sankey chart of a building shows that majority of the heat is lost through the walls, it is easier to prioritize insulation improvements over, say, upgrading the heating system.

Moreover, Sankey charts help to:

  • Identify Waste: By visualizing unnecessary or excessive energy use or resource consumption, they point to opportunities for waste reduction.

  • Predict Future Trends: By showing how flows change over time, they provide a predictive window for future improvements and adaptations.

  • Compare Systems: Sankeys enable the comparison of different systems or processes, helping decision-makers to understand the differences and similarities.

Sankey charts have proven themselves as essential tools in the field of data visualization, transforming intricate systems of flows into legible, compelling stories. As data continues to surge, the value of tools like Sankey diagrams will only grow, ensuring that we stay afloat in the river of data flow with clarity and insight.
