Sankey charts are a powerful tool for analyzing and visualizing complex data flows. They provide a clear insight into relationships between various elements of a system, in contrast to traditional diagrams that may not be as intuitive or visually appealing. In this article, we’ll explore the power and beauty of Sankey charts, providing an in-depth look at their applications, creating a guide for beginners, and answering common questions about this type of data visualization.

What is a Sankey Chart?

A Sankey chart is a type of diagram that displays the flow of data. It has a flow line (or “link”) for each type of data, with arrows to indicate the direction of the flow. It is based on a type of diagram called a channel diagram.
The key elements of a Sankey chart are:

• Nodes: These represent the various types of data being analyzed, such as sales, customers, or orders.
• Links: These represent the data flow between the nodes. Each link can be labeled with a value or function to describe the direction and type of flow.
• Labels: These represent important data such as the source node and the destination node.
• Color and style: Sankey charts can be customized in many ways, including color and style, to better represent different types of data or highlight important elements.

Sankey charts have several applications:

1. Data analysis: Sankey charts can help identify trends and patterns in complex data sets.
2. Project management: Sankey charts can be used to track the flow of resources from one department to another, showing which departments are essential and which steps need attention.
3. Business intelligence: Sankey charts can be used to visualize data from various sources and compare them in a single, easy-to-read diagram.
4. Human resources management: Sankey charts can be used to track employee performance and identify areas where improvement is needed.

How to create a Sankey chart

Creating a Sankey chart requires knowledge of the data being analyzed and a good understanding of the structure of the information. Here are the basic steps of creating a Sankey chart:

1. Define the data you want to visualize
2. Organize the data into categories or types (source nodes and destination nodes)
3. Determine the direction of the flow by assigning each link a value (source or destination)
4. Add labels to each node and link to describe the data flow and function
5. Customize the color and style of the diagram to better represent different areas of the data

To create a Sankey chart, you can use software like Microsoft Visio, PowerPoint, or Google Drawings. You can also use online tools like Sankeycharts.com, which makes it easy to create your diagram.

Conclusion

Sankey charts are a powerful tool for visualizing complex data in a clear and intuitive way. They provide a clear insight into the flow of data and allow for a deeper understanding of the relationships between different elements. Whether you’re a data analyst, business manager, or project leader, Sankey charts can help you organize your data in a more efficient and effective way.
