Sankey charts are a powerful tool for visualizing complex data relationships in a way that is easy to understand. They are particularly useful in a wide range of fields, including management consulting, engineering, and finance. In this article, we will briefly guide you on how to create and apply a Sankey chart for more efficient data visualization.
What Is a Sankey Chart?

A Sankey chart is a type of chart that uses a directed line graph to represent the flow of data. It is a simple but effective way to visualize the flow of information or resource between different entities or categories. To create a Sankey chart, you should define the source and target entities of the flow, and then connect them with directed lines. Each line represents a specific type of data flow (for example, inputs, outputs), and the length of the line corresponds to the amount of flow.
How to Use Sankey Charts

Sankey charts are very useful for visualizing complex data flow relationships. Here are a few things you should consider when using Sankey charts:
1. Define the data flow elements: Before creating a Sankey chart, you need to define the data flow elements that you want to visualize. These elements can include inputs, outputs, processes, and more. Make sure to pay attention to the data flow direction, as this can have a big impact on the flow of data.
2. Choose the appropriate representation: Sankey charts can be presented in many ways, such as a diagram, a flowchart, or a network diagram. Choose the representation that best suits your needs and the data flow relationships you want to visualize.
3. Adjust the scale: Be sure to adjust the scale of the Sankey chart so that the data flow relationships are clearly visible. You may need to experiment with different scales to find the optimal representation for your data flow relationships.
4. Add labels: Adding labels to the Sankey chart can help you understand the data flow relationships more easily. Label each source and target node, and add descriptions to the lines to give more information about the data flow.
Examples

Here are a few examples of how to create and apply Sankey charts:

1. A Sankey chart can help visualize the flow of customers through a company’s sales system. Here’s an example of a Sankey chart showing the flow of customers from the sales department to the customer service department:

2. A Sankey chart can be used to visualize the flow of information between a group of researchers. Here’s an example of a Sankey chart showing the flow of ideas between the researchers:

3. A Sankey chart can help visualize the flow of inputs and outputs in a project. Here’s an example of a Sankey chart showing the flow of inputs and outputs between the project team members:

   Conclusion

   Sankey charts are an effective way to visualize complex data flow relationships. By defining the data flow elements, choosing the appropriate representation, adjusting the scale, and adding labels, you can create a Sankey chart that is easy to understand and visualizes your data flow relationships clearly.
