Sankey charts are a type of data visualization that are used to show the flow of materials, energy, or information between different entities. They are especially useful for showing the dependencies and relationships between different factors. In this article, we will explore how to create Sankey charts, and the various applications of this type of visualization.
Creating Sankey Charts
Sankey charts can be created using a variety of tools, such as Microsoft Excel, PowerBI, Tableau, or charting libraries in web development. One of the main advantages of using a Sankey chart is that it allows you to easily visualize complex relationships between different entities.
To create a Sankey chart in Excel, for example, you can use the Sankey chart template. Simply select the data that you want to visualize and open the chart template. From there, you can customize the chart by changing the colors, styles, and other settings to suit your needs.
Another option for creating Sankey charts is to use a data visualization library in a web development framework such as D3.js or Highcharts. These libraries provide a range of functions for creating Sankey charts, including the ability to customize the chart’s appearance and use interactivity to explore the data.
Applications of Sankey Charts
Sankey charts are particularly useful for visualizing the relationships between different entities in complex systems. Some examples of the types of data that can be visualized using Sankey charts include:
- Energy flow in a system, such as the flow of energy between different types of industries
- Material flow in a manufacturing process
- Information flow between different departments or teams within an organization
In addition to their use in analyzing complex systems, Sankey charts are also useful for demonstrating the flow of data in real-time. For example, they can be used to show the flow of data between different stages of a website’s conversion process, or the flow of data between different pages on a website.
Overall, Sankey charts are a powerful tool for visualizing complex data relationships. They are easy to create and use, and can be customized to suit a wide range of applications. Whether you are analyzing a complex system or demonstrating a real-time data flow, Sankey charts can help you gain insights into the relationships between different entities.
