Sankey charts are an advanced form of data visualization used to represent the flow and transformation of data. They are particularly useful for visualizing complex network structures and identifying patterns and relationships between different data points. In this guide, we will discuss everything you need to know to create and use Sankey charts effectively.

What is a Sankey Chart?

A Sankey chart is a type of flow chart that is used to show the direction and magnitude of the flow of items between nodes. It is named after its creator, Lawrence Sankey, who introduced the chart in 1931. Sankey charts are particularly useful for visualizing the flow of goods, services, or financial transactions, as well as the relationships between different data points.

How to Create a Sankey Chart

To create a Sankey chart, you will need to use a software that supports the creation of Sankey charts, such as Microsoft Visio, Lucidchart, or Draw.io. Once you have chosen your software, you can follow these steps to create your Sankey chart:

1. Start by creating the nodes for your chart. Each node represents a data point, such as a country, region, or category.
2. Connect the nodes using arrows to indicate the flow of data between them. The arrows have two endpoints: the source and the sink. The source represents the input or origin of the flow, while the sink represents the output or destination of the flow.
3. Customize the appearance of the chart by adjusting the colors, styles, and labels of the nodes and arrows.
4. Save the chart to your desired format and print it out if necessary.

Applications of Sankey Charts

Sankey charts are a powerful tool for visualizing complex network structures, and there are many different applications for Sankey charts in data visualization. Here are just a few examples of the types of data that can be visualized using Sankey charts:

1. Supply chain management: Sankey charts can be used to visualize the flow of goods or services between different suppliers, distributors, or customers.
2. Financial transactions: Sankey charts can be used to visualize the flow of money between different accounts or individuals, as well as the relationships between different financial instruments or assets.
3. Customer acquisition: Sankey charts can be used to visualize the flow of customers or leads through different stages of the sales process, such as the initial inquiry, the sales proposal, and the final purchase.
4. Social networks: Sankey charts can be used to visualize the flow of information or connections between different individuals or groups within a social network.

Conclusion

In conclusion, Sankey charts are a powerful tool for visualizing complex network structures and identifying patterns and relationships between different data points. They are particularly useful for applications such as supply chain management, financial transactions, customer acquisition, and social networks. By using a software that supports the creation of Sankey charts, you can easily create and customize your own charts to meet your specific needs.
