Title: Visual Symphony: Deciphering Complex Relationships with Sankey Diagnostics

Introduction

In the era of big data and information overload, the ability to present complex systems and relationships clearly and coherently has become paramount. Graphs and charts serve not just as representational tools, but as conduits for the comprehension of intricate data patterns. One such visual methodology harnesses the power of arrows and nodes to paint a picture of flow and connection: Sankey Diagnostics, affectionately known as Sankey charts. This article delves into the principles of creating and applying Sankey charts, drawing on their unique strengths for illuminating complex systems and relationships.

What are Sankey Diagnostics?

Sankey charts, named after their creator, Albert V. Austin Sankey, are a type of flow diagram. These charts utilize a diagrammatic technique where the thicknesses of the sections of shapes are proportional to the quantity represented. They are particularly useful for illustrating the flow of work, energy, information, or costs among different business functions, departments, or systems.

Sankey chart elements

A typical Sankey chart comprises three primary components:

  1. Nodes: Nodes represent the origin, destination, or intermediary points in the process. They are the entities that either consume or generate a part of the flow based on the data.
    2.Links: Links, typically made up of directional arrows, signify the flow between nodes. The width of the links represents the quantity or proportion of the flow, allowing for a clear visualization of how much is being allocated or transferred.
  2. Labels: Labels commonly encased below or beside the links give quantitative information about the flow. These are essential for translating the thickness of the links into concrete numeric values.

Sankey chart creation basics

Creating an effective Sankey chart begins with careful data collection and analysis. Here’s a fundamental step-by-step guide:

  1. Define your Objective: Clearly outline the question or issue you’re addressing with Sankey charts. Are you looking to optimize your production process, deciphering the energy consumption, or illustrating the data flow across different departments?

  2. Collect and Preprocess Data: Gather the raw data that pertains to your objective. This could include numbers related to energy consumption, product flow, or financial transactions. Then, calculate proportions if required and ensure that your data is sorted and ready for visualization.

  3. Map Out the Flow: Trace the flow of data and map out the major nodes (starting and ending points). This mapping will shape the overall structure of your Sankey chart.

  4. Create the Base Chart: Employ a diagramming tool or software like Microsoft Power BI, Tableau, or open-source libraries like Sankey and D3.js. Input the nodes, links, and corresponding data labels as per your mapped flow.

  5. Adjust for Aesthetics and Readability: Fine-tune the thicknesses of the links to accurately represent your data. The alignment of nodes and links should also be made to improve the aesthetic and make the flow easy to follow.

Applications of Sankey charts

  1. Energy Consumption Analysis: Sankey charts are a powerful tool for visualizing energy flows within an organization or a building, illustrating where efficiency improvements can be made.

  2. Supply Chain Visualization: By mapping out supply chain components, Sankey diagrams help in understanding potential bottlenecks and streamlining operations for better supply chain management.

  3. Financial Tracking: Financial flows within an organization, such as budget allocations, cost distributions, revenue streams, etc., can be clearly represented through Sankey charts, aiding decision-making processes.

  4. Environmental Impact: These charts can also be used to illustrate natural resource consumption and emissions, aiding in the sustainability goals of an organization.

Conclusion

Sankey charts are more than just visual aids; they are navigational tools that provide a sense of the ‘big picture’ while also pinpointing the details. By clearly delineating the flow and connection among different variables, they offer a dynamic means to interpret and communicate complex systems and processes. No longer does information overload need to stifle insights. With the simple yet profound technique of Sankey Diagnostics, even the most intricate relationships can be unraveled and shared with clarity, thus enabling meaningful dialogue and informed decision-making.
