Streamlined Insights: The Unspoken Power of Sankey Charts

In the world of data visualization, the Sankey chart quietly resides as an underutilized power player that can reveal complex insights in a simple and intuitive way. Despite their somewhat uncommon presence in standard data presentations, Sankey charts are a treasure trove of information that can help organizations transform data into actionable knowledge. Here’s an in-depth guide on the creation and applications of Sankey charts, demonstrating the unseen potential they possess.

What is a Sankey Chart?

At the simplest definition, a Sankey chart is a flow diagram where an arrow’s thickness depicts the scale of flow within the system. These diagrams are especially beneficial for illustrating the flows of energy, materials, cost, and people within various systems. While they might not be everyone’s go-to chart type, when it comes to understanding large-scale flows, Sankey charts are unparalleled.

Building Blocks: Creating a Sankey Chart

  1. Identify Your Flow: Start by defining what you want to track. This could be energy flow within energy systems, money allocation in business models, or the water flow in an ecological system.

  2. Break Down the Path: Divide the process into segments, which should clearly depict the various steps or nodes within your flow. Ensure each node is distinct and represents a different stage.

  3. Determine Your Flow Units: Establish what constitutes your unit of flow. This could be megawatts, dollars, kilograms, or anything relevant to your data.

  4. Assign Arrow Widths: The width of each arrow reflects the flow unit. In high-flow segments, the arrow will be thick, and in low-flow segments, it will be narrow. The thicker the arrow, the greater the quantity of flow at that point.

  5. Connect Nodes: Link the nodes with arrows, maintaining consistency in the flow direction throughout. Ensure that the endpoints of each arrow are precise and clearly connect two nodes.

  6. Normalize and Validate Data: Ensure that your data is accurate and representative of the system you’re analyzing. Sankey charts can mislead if not based on sound assumptions and data collection.

  7. Label and Maintain Clarity: Assign meaningful labels to each node, and if possible, assign color coding for readability and additional information. However, avoid cluttering the chart with too many labels or explanations.

  8. Finalize with a Story: Sankey charts work best when they tell a story. Use narratives within your text or presentation to guide the viewer through the key insights that the chart reveals.

Applications of Sankey Charts

The versatility and clarity of Sankey charts make them suitable for a variety of applications, including:

  • Energy Systems: Analyzing energy consumption by different appliances or in various stages of production can be visualized with a Sankey chart to identify inefficiencies in energy distribution.

  • Financial Flows: Tracking the flow of money in a business or across sectors can reveal insights into how and where resources may be misspent.

  • Supply Chains: Visualizing the movement of materials or products through a supply chain can help identify bottlenecks and streamline operations.

  • Ecosystems: Monitoring biodiversity or water flow through ecosystems can lead to better environmental management and conservation strategies.

  • Information Flow: In a technological context, understanding how information is transmitted between systems can enhance data management and reduce errors.

  • Transportation Networks: Analyzing traffic flow or the movement of goods and passengers can optimize transportation systems and logistics.

The Power Within

The unspoken power of Sankey charts lies in their ability to make complex data flows intuitive and accessible. These diagrams bridge the gap between abstract data and tangible insights that can lead to better decision-making and strategic planning. While they may have been overlooked in certain circles, the emergence of advanced data visualization tools has renewed the popularity and efficacy of Sankey charts.

For those looking to simplify complex systems and extract meaningful insights, learning how to create and utilize Sankey charts is a valuable addition to any analytical toolkit. With their ability to tell visual stories of the intricate flow of resources, Sankey charts have become a powerful ally in the quest for streamlined insights.
