In today’s digital world, data analysis has become an essential part of decision-making. Sankey charts, a type of chart that helps in visualizing a network of relationships, are increasingly being used to represent such data. A comprehensive guide to Sankey chart creation and applications can help individuals in organizing, analyzing, and visualizing data more effectively.

Basic Understanding of Sankey Charts

Sankey charts are type of charts that use line segments to represent flows or connections between nodes or elements in a system. The lines are connected to the nodes and have a width proportional to the amount of flow. This type of chart is ideal for representing relationships between elements, making it particularly useful for data analysis.

A Sankey chart consists of two main components:

• Nodes: These are the elements in your network that has the flow represented by the lines between them.
• Edges: These are the lines connecting nodes. They represent the direction of the flow, and the width of the edge represents the amount of flow.

Applications of Sankey Charts

Sankey charts are commonly used in finance, engineering, and engineering. The three main applications of Sankey charts are:

1. Network Analysis: Sankey charts can be used to analyze and visualize the relationship between various elements in a network. In finance, for instance, Sankey charts can be used to show the movement of capital and investment in a company.
2. Process Flow: Sankey charts can also be used to represent the movement of data or information in a process. This can help streamline the process and identify bottlenecks and areas for improvement.
3. Data Visualization: Sankey charts can also be used to visualize data in an easy-to-understand manner. They make it easier to spot patterns and trends in the data.

Sankey Chart Creation

Creating a Sankey chart is relatively simple but requires a basic understanding of data visualization. Here are the steps:

1. Collect your data: Collect the data you want to visualize. Ensure it is clean and accurate.
2. Choose your data: Choose the nodes you want to include in your chart. You can either manually add nodes or import them from a spreadsheet or other source.
3. Identify your edges: Determine the direction of the flow and where they lead to. You can choose to show all edges or only the ones that are significant for the analysis.
4. Layout the chart: Once you have your data and edges, plot them on a piece of paper or a digital tool. There are several tools available for creating sankey charts, such as Microsoft Visio, Microsoft Power BI, and Canva.
5. Customize your chart: Use the tools available in your selected software to customize your chart. This includes adding labels, colors, and fonts.

Sankey Chart Examples

Here are some examples of how Sankey charts can be used to visualize data:

• Credit Flow: Imagine a company with several clients. You could use a Sankey chart to visualize the flow of capital and investment between the company and its clients.
• Manufacturing Process Flow: If you’re working on a manufacturing process, you could use a Sankey chart to visualize the movement of materials and products through the process.
• Resource Flow: In the context of environmental sustainability, you could use a Sankey chart to visualize the flow of resources like water and energy.

Conclusion

Sankey charts are a powerful tool for data visualization and analysis. They can help you spot patterns and trends in your data, streamline your processes, and make better-informed decisions. With a bit of practice and creativity, you can use Sankey charts to create a clear and well-designed visual representation of your data.
