Sankey charts are a powerful data visualization tool that allow you to clearly see the flow and relationships between different data points. They are particularly useful for visualizing complex data networks, such as supply chain operations or financial transactions. In this article, we will explore the creation of Sankey charts and some of the ways they can be used to gain insights from data.
What is a Sankey chart?
A Sankey chart is a type of flowchart that is used to show the direction and magnitude of a flow between different nodes. Each node represents a data point, and the flow between nodes is shown by arrows connecting them. The arrows have two endpoints: the source (the point from which the flow originates) and the sink (the point to which the flow ends).
The unique feature of a Sankey chart is the ability to clearly see the flow and relationships between different data points. This is made possible by using color, size, and shape to represent the magnitude of the flow. For example, a large flow can be represented by a larger arrowhead, while a small flow can be represented by a smaller arrowhead. This allows for quick and easy comparisons between different data points.
Sankey chart creation
Sankey charts can be created in a variety of software programs, including Microsoft Excel, Lucidchart, and Coggle. To create a Sankey chart, follow these steps:
- Open your chosen software program and create a new chart.
- Select the type of chart you want to create (a Sankey chart).
- Add the nodes and arrows to your chart using the chart editor.
- Customize the chart by adding colors, shapes, and other decorations as desired.
- Save the chart to your desired location.
Applications of Sankey charts
Sankey charts are a versatile visualization tool that can be used in a variety of applications, including supply chain management, financial analysis, and social network analysis. Some of the ways Sankey charts are used include:
- To visualize the flow of goods or services through a supply chain, showing how they move from one node to another and the total amount of each item.
- To show the flow of funds or assets through a financial system, such as a bank or investment fund.
- To represent the connections between people or groups on a social network, showing how ideas or information move between them.
In addition to these applications, Sankey charts can also be used to visualize other types of data networks, such as scientific experiments or information retrieval systems.
Conclusion
Sankey charts are a powerful data visualization tool that allow you to clearly see the flow and relationships between different data points. They are particularly useful for visualizing complex data networks, such as supply chain operations or financial transactions. With their ability to display flow, color, size, and shape, Sankey charts provide a comprehensive view of data networks, making it easy to gain insights from complex data.
