Introduction

In the world of data visualization, Sankey charts are a powerful tool that can help you to understand complex data and communicate your insights in a clear and effective way. Sankey charts are a type of bar chart where each node represents a data value and the flow between nodes represents the direction and magnitude of the data flow. This makes them particularly useful for visualizing flow graphs, such as supply chain networks, resource allocation, or data flow analysis. In this article, we will explore the visual power of Sankey charts and provide you with a guide to understanding and using them in data visualization.
Sankey Chart Creation

Sankey charts are created using a layout process called the “flow chart algorithm.” The algorithm starts by creating a set of nodes and flows, where nodes represent the different data values and flows represent the data flow between these nodes. The algorithm then uses a series of rules to calculate the flow direction and magnitude of the data flow, taking into account the data values and their relative values. The resulting Sankey chart is a clear and easy-to-understand representation of the data flow.
Sankey Chart Applications

Sankey charts have many applications in data visualization, including supply chain networks, resource allocation, and data flow analysis. In a supply chain network, the nodes represent products or services, and the flows represent the movement of goods or services between these nodes. In resource allocation, the nodes represent different resources, such as labor or equipment, and the flows represent the flow of resources from one node to another. In data flow analysis, the nodes represent different data flows, and the flows represent the direction and magnitude of these flows.
Conclusion

Sankey charts are a powerful tool for visualizing complex data and communicating your insights in a clear and effective way. By understanding the layout process of the Sankey algorithm, you can use Sankey charts to create complex flow graphs and provide a clear understanding of the data flow in your data visualization. Whether you are working on a supply chain network, resource allocation, or data flow analysis, Sankey charts can help you to analyze your data and communicate your insights in a way that is easy to understand. So, give it a try and explore the visual power of Sankey charts in your data visualization projects.
