Title: Visualizing Invisible Flows: The Sankey Principle Simplified

Introduction:
The flow of resources can often be a complex and largely invisible aspect of our lives. From energy production to logistics distribution, countless transactions and exchanges pass unseen. Introducing the Sankey diagram: a visual tool that uncovers the flow and magnitude of these intangible resources. In this article, we’ll tackle the Sankey chart creation process and unveil its expansive applications across various sectors.

Understanding Sankey Charts:
Sankey charts are flowcharts that use arrows to represent the flow of goods or flows of energy. Developed by British mathematician and engineer Bertie Charles William Sankey in the 1930s, these diagrams efficiently display the quantitative flow of values between states by highlighting the relative contribution of each link. The fundamental principle of Sankey charts is the use of area to provide a visual comparison of flow volumes across the chart.

Creating a Sankey Chart:
To start making a Sankey chart, you first need a software tool to construct this type of diagram. Open source libraries like JavaScript’s Sankey, or more comprehensive software such as Microsoft Excel, are handy tools to employ. The process generally goes as follows:

  1. Input Data: Before drawing a Sankey, you must compile data related to the process or flow to visualize. This may include quantities of each type of resource involved, the number of units transferred over a certain period, or the energy dissipated.

  2. Identify Nodes: The nodes represent the sources and destinations of the flow. For example, in an energy system, the sources might be energy production sites, while destinations could be consumers such as homes or businesses.

  3. Calculate Edge Weights: Each arrow in the diagram represents an ‘edge’, and its weight corresponds to the magnitude of the flow between nodes. These weights are calculated based on your collected data and are used to determine the length of each arrow.

  4. Determine Flow Direction: Determine the direction of the flows. This is usually in line with the flow of energy or resources, moving from sources outward to destinations.

  5. Configure the Layout: The layout of these graphs can be customized to fit specific needs. For instance, you could design the chart so that arrows point towards the sink node (the node with the lowest value), from which all other flows emanate.

Applications of Sankey Charts:
The diverse applications of Sankey charts make these diagrams invaluable in various fields. Below are a few examples:

  1. Energy Sector: These charts help illustrate the source of energy input and energy output, and can provide insights into energy loss and efficiency improvements.

  2. Business Analytics: In business environments, Sankey charts can be used to display the flow of capital from an investor’s perspective, showing the distribution of the capital within a company’s different projects or products.

  3. Logistics and Supply Chain: In manufacturing and distribution, these charts can elucidate the flow of materials through the supply chain, presenting potential bottlenecks or redundancies, thereby facilitating optimization.

  4. Environmental Science: Environmental Sankey charts can highlight the flow of pollutants through ecosystems, the source of raw materials, and the impact of human activities on the environment.

Conclusion:
Sankey charts provide a comprehensive visualization of invisible flows, transforming complex data into a clearer and more easily understood visual display. By shedding light on the quantity and direction of flows between various system entities, businesses, policymakers, and scientists can make more informed decisions. With its flexibility and broad utility, it’s no wonder that the Sankey chart is a powerhouse in the toolkit of data visualization. As we continue to grapple with the myriad flows of resources in our interconnected world, the Sankey chart stands poised as an invaluable, user-friendly tool for dissecting and presenting these intricate networks.
