Sankey charts, also known as a digraph, are a type of network diagram that is often used in data analysis to visualize relationships between different entities and their flows of data. These charts are particularly useful when there are multiple layers of data, and where different sources or sinks are involved in flows of data. In this article, we will explore the benefits of using Sankey charts to unleash the power of data analysis and to visualize relationships more effectively.
The Benefits of Sankey Charts

Sankey charts are particularly useful in data analysis for several reasons:

1. They help to visually represent complex and interwoven relationships between entities. With a traditional network diagram, the relationships between entities appear disorganized and may not be evident.

2. Sankey charts make it easy to identify the direction of flows. This is particularly useful when you want to analyze the directionality of flows, especially when flow is either positive or negative.

3. They provide a high-degree of control over the layout of the chart. Sankey charts allow you to customize the layout to suit your needs, ensuring that the flow of information is clear and easily understandable.

Applications of Sankey Charts

Sankey charts can be used in various applications, including:

1. Analyzing economic flows: Sankey charts can be used to visualize the flow of economic data such as trade, investment, and consumption.

2. Analyzing political flows: Sankey charts can be used to visualize the political relationship between different political entities, such as parties, candidates, and the state.

3. Analyzing social flows: Sankey charts can be used to visualize the social relationship between different social groups.

4. Analyzing organizational flows: Sankey charts can be used to visualize the flow of information and resources within an organization.

Conclusion

Sankey charts are an excellent tool for data analysis. They provide a clear, easy-to-understand representation of complex relationships between entities. With the ability to customize the layout of the chart, and the option to display directionality, they provide a high-degree of control over the chart. With the increasing use of computer software, creating Sankey charts is relatively easy, and with the help of software such as Tableau or Microsoft Excel, it can be done without too much difficulty. As a result, Sankey charts have become an essential tool for data analysis, and they continue to play significant roles in all areas of data analysis.

In summary, Sankey charts provide a high-degree of control over the layout and directionality of flows. They are particularly useful in data analysis and provide a clear and easy-to-understand representation of complex relationships between entities.
