Sankey charts have become a popular tool for visualizing complex relationships in data. These charts are particularly useful for illustrating the key relationships between different data points or processes. In this article, we will take a look at how to create and understand Sankey charts, and what makes them useful for understanding key relationships in data.
What is a Sankey Chart?
A Sankey chart uses a series of interlocking arcs to represent dependencies and relationships between different data points or processes. The arcs are typically connected by line segments, which represent how much flow or flow rate between the two points. The length of the line segments indicates the amount of flow, and the color of the arcs helps differentiate between different types of relationships.
Sankey charts are particularly useful for visualizing the relationships between different variables in a dataset. This can be particularly useful for applications like supply chain management, where the relationships between different components or processes are complex and difficult to visualize using traditional charts like line graphs or bar charts.
How to Create a Sankey Chart
Creating a Sankey chart requires a few basic steps:
1. Identify the variables or processes you want to visualize. These could be related to supply chain management, manufacturing processes, or any other type of data you are working with.
2. Organize your data by grouping related variables or processes together. For example, you might group the manufacturing processes in your supply chain that are involved in producing a particular component together.
3. Decide on the flow rates you want to represent. These could include things like the flow rate for different production steps, or the amount of inventory flow between different components in your supply chain.
4. Create a series of interlocking arcs for each flow rate you want to depict. Each arc should connect to the parent variable or process and to the child variables or processes.
5. Plot the arcs on your chart, and use connecting lines to indicate the flow rates.
6. Color the arcs to differentiate between different types of relationships. For example, you might use different colors to indicate flow rates and different types of relationships between the components in your supply chain.
Some Tips for Understanding Sankey Charts
1. Start with basic shapes: Sankey charts can be a bit intimidating at first, especially if you’re new to them. Start with simple shapes like small circles or triangles to represent different types of relationships between the variables.
2. Use labels and legends: Sankey charts can be difficult to understand without labels and legends. Label each variable or process in your chart and use a legend to indicate the meanings of the different line segments.
3. Look for patterns: As you become more familiar with Sankey charts, you’ll start to notice patterns in the relationships between the variables. Look for trends or patterns in the flow rates and make notes of any insights you can find.

In conclusion, Sankey charts are a powerful tool for visualizing complex relationships between different variables in data. By following the steps outlined in this article, you can create Sankey charts that accurately and accurately depict the relationships between the variables in your dataset.
