Sankey chart is a visual representation technique used to visually represent data flows or resource flows. It was first introduced in 1933 by American civil engineering professor G. W. Searcy, and is one of the most widely used visualization techniques in today’s data-driven era. The main purpose of a sankey chart is to provide an easy-to-understand representation of the flow of information from one source to another in a network, without considering the direction of the data flow. In this article, we will explore the power of sankey charts, their benefits, and applications in various fields.
Benefits of Sankey Chart
Sankey charts are highly useful in various fields and applications. Here are some benefits of sankey charts:
-
Quick visualization: A sankey chart can quickly visualise complex data patterns and data flows. This makes it easier for the user to understand the data flow from one point to another without considering any specific direction.
-
Easy interpretation: Sankey charts make it easy to understand the flow of data or resources without any specific direction. It can also help in understanding the direction of incoming and outgoing flows.
-
Facilitating decision making: Sankey charts provide a clear and concise visual representation of the data flow, making it easier for the user to understand the data patterns and the direction of flow in the network. This can help in the decision-making process by providing the data flow patterns in a more intuitive way.
Applications of Sankey Chart
Sankey charts are widely used in various fields, including finance, computer science, and social science research. Here are some common applications of sankey charts:
-
Supply chain management: Sankey charts can be used to visually represent the flow of goods and services from suppliers to customers in a supply chain management system. This helps in understanding the direction of the flow of goods and services and makes it easier to optimize the supply chain.
-
Network analysis: Sankey charts can be used to visually represent the flow of information or data in a network. This can help in understanding the direction of the flow of information and making informed decisions about the network’s structure.
-
Marketing analysis: Sankey charts can help marketers understand the flow of product information in their marketing campaign. This can help in understanding the direction of the flow of information to customers and optimizing the marketing campaign.
Conclusion
Sankey chart is a powerful visualization technique used to visually represent data patterns and data flows. It provides a clear and concise representation of the data flow, without considering direction. Sankey charts can be used in various fields, including finance, computer science, and social science research. In summary, sankey charts are a valuable tool in visualizing complex data patterns in a clear and concise way.
