Sankey charts, also known as directed flow charts, are an effective way to visualize the flow of data in a network. They are particularly useful for showing the direction of causality between different items or entities. In this article, we will explore how to create Sankey charts, their applications, and some best practices to ensure effective data visualizations.
Creating Sankey Charts
Sankey charts are created using specialized software or online tools. However, there are also several options available for creating them manually. Here are the steps to create a Sankey chart:
- Determine the direction of the flow: In Sankey charts, the flow is always from left to right. You should decide which direction the flow direction will be before you start creating the chart.
- Identify the data source: Identify the data source that you want to visualize. This should include information about the different entities, their properties, and the flow between them.
- Gather the data: You should gather all the necessary data to create the chart. This may include data about the source,destination of flows, the type of flow, or any other relevant variable.
- Create the chart: Use the software or online tool to create the chart. You should specify the direction of flow, the different entities, their properties, and any other relevant details.
- Customize the chart: Once the chart is created, you can customize it to make it more effective. This may include adding titles, graphs, or other visual elements.
Applications of Sankey Charts
Sankey charts are widely used for data visualization purposes, particularly in fields such as finance, engineering, and network analysis. Here are some applications of Sankey charts:
- Flow analysis: Sankey charts are particularly useful for showing the flow of data in a network. They can be used to analyze the direction and magnitude of flows, identify bottlenecks, and optimize the flow of data.
- Process modeling: Sankey charts can be used to model complex processes, showing the flow of data and the causal relationships between different steps. This can be helpful in understanding the overall process and identifying areas for improvement.
- Supply chain management: Sankey charts can be used to visualize the flow of goods and services through a supply chain. This can be helpful in identifying areas for improvement, optimizing processes, and tracking inventory.
- Financial analysis: Sankey charts can be used to visualize the flow of funds in a financial system. This can be helpful in identifying areas for improvement, optimizing processes, and tracking assets.
Best Practices for Effective Data Visualization
To ensure effective data visualization, it is important to follow best practices. Here are some best practices for creating Sankey charts:
- Use clear and concise labels: Labelling the chart elements and connecting them to the source and destination of flows is crucial. Make sure to use clear and concise labels that are easy to understand.
- Keep the chart simple: Sankey charts can be complex, but it is important to keep them simple. Use clear colors, labels, and simple graphics to make the chart easy to understand.
- Use the right scale: Using the right scale can make a big difference in the effectiveness of the chart. Make sure to choose a scale that is appropriate for the data and the chart elements.
- Use relevant data: Make sure to use relevant data that accurately reflects the flow of data in the network. This can help make the chart more effective and informative.
- Customize the chart: Customizing the chart can make it more effective. This may include adding graphs, tables, or other visual elements that help to clarify the flow of data.
Conclusion
Sankey charts are a powerful tool for visualizing data in a network. They are particularly useful for showing the flow of causality between different items or entities. To ensure effective data visualization, it is important to follow best practices for creating Sankey charts. By using clear and concise labels, keeping the chart simple,using the right scale and customizing the chart, you can enhance your data visualization game and make your data more accessible and actionable.
