Introduction:

Sankey charts have become an increasingly popular visual representation tool for visualizing complex data. These charts are known for their visual simplicity, making it an ideal tool for explaining intricate relationships between variables. This article delves into how to create and apply sankey charts to communicate complex data.
Step 1: Determine Your Data

Before turning to an sankey chart, it’s essential to have clear data set. Define the variables that you want to represent, and ensure that the data is accurate and complete. The quality of your data will be the main determinant of the effectiveness of the visualization.
Step 2: Design Your Chart

The design of the sankey chart is equally critical to its effectiveness. Use a clear, consistent color scheme for the various variables, and decide the direction of their flow. You can also choose a gradient that matches the direction of the data flow, making it easier for viewers to interpret.
Step 3: Determine the flow direction

Next, decide which direction the data will flow. A clear flow direction can help viewers understand the relationships between variables. You can choose between three main directions: upward, downwards, or from right to left. The direction of orientation can greatly affect the viewer’s perspective.
Step 4: Connect the variables

The key to a sankey chart’s effectiveness is the connections between variables. It’s essential to connect each variable node to a matching node in another variable. You may also want to use an arrow to indicate the direction of flow or use color codes to symbolize different flows.
Step 5: Add labels and descriptions

Labels and descriptions are crucial for adding contextual information that can help viewers understand the data. Label each variable and provide concise descriptions of the data. You can also use annotations to highlight important data points for a closer insight into the complex data.
Step 6: Display the Final Visualization:

Finally, save your sankey chart and display it as per your requirements. You can use a web-based Sankey charts tool like Sankey.io, which can be customized to meet your needs.
Applications:

Sankey charts are widely used in fields such as economics, social sciences, and environmental engineering. They are particularly effective at showing how different variables interact with each other. For example, a graphic designer might use a sankey chart to visualize the customer segment that drives specific marketing campaigns.

Conclusion:

Sankey charts are an excellent visualization tool for complex data. They are effective as they present data in an intuitive and easy-to-understand way, making it suitable for communicating data to individuals, groups, or teams. By following these steps, you can create the ideal sankey chart that aligns with your data set, flow direction, and visual design requirements.
