Sankey charts provide a unique visual representation of data flow, allowing users to easily identify patterns and trends in the movement of material, energy, or information through a system.
The origin of Sankey charts dates back to the late 19th century, when they were designed to show energy consumption in steam engines. Today, these charts can be used in a wide range of industries, from finance to logistics, to illustrate complex relationships between different components in a system.
Creating a Sankey chart involves several steps. First, you must define the system you want to represent. This means identifying the nodes (or vertices) in your system—the sources, destinations, and points of interchange—and the flows between these nodes. The flows can be represented by arrows, and the width of the arrows can indicate the magnitude of the flow between each node.
Next, you’ll need to gather your data. This data could come in the form of lists of flows between nodes, or you could calculate it based on other data in your system. When entering your data, it’s important to establish a clear relationship between the nodes and flows. For example, in a logistics system, you might have nodes representing different warehouses and flows representing the transportation of goods between them.
Once your data is ready, you can create your Sankey chart using various software tools, such as Microsoft Excel, Tableau, or even the Python library Plotly. Each software has its own methods for inputting data and creating the visual representation, but they generally involve configuring the size, color, and style of the nodes and flows.
Finally, it’s essential to analyze your Sankey chart to uncover insights. This might involve identifying bottlenecks in the flow, spotting unusual patterns, or determining the efficiency of the system. Visualizing your data in this way can make it easier to communicate your findings to others, facilitate decision-making, and identify areas for improvement.
Sankey charts have a wide range of applications across various industries. In finance, they can be used to show the flow of capital between different market segments or transaction types. In the field of energy, Sankey diagrams help illustrate energy consumption and production patterns across an entire economy. For logistics and supply chain management, they provide a clear visual representation of the flow of materials, identifying areas that may be prone to waste, inefficiencies, or bottlenecks.
By using Sankey charts, professionals can gain a deeper understanding of the complex systems and patterns within their industries. The ability to see the flow of material, energy, or information across interconnected components has become increasingly valuable in today’s data-driven world, enabling better decision-making and more effective optimization of resources.
In conclusion, Sankey charts provide a powerful tool for visualizing and understanding complex data flow patterns. By following the steps of defining your system, gathering data, creating the chart, and analyzing the insights, professionals across various industries can gain valuable insights into the workings of their systems, enhancing their decision-making skills and improving overall system efficiency.
