Sankey charts are a type of flowchart that are particularly useful for showing the flow of goods, services, or information between different entities. They are often used in data visualization to show the relationships between different variables, and can help to identify bottlenecks, inefficiencies, and opportunities for improvement.
In this article, we will provide a step-by-step guide on how to create Sankey charts and use them effectively for data analysis. Whether you are a beginner or an experienced data analyst, this article will help you to understand the basics of Sankey chart creation and how to apply them to your data.
Step 1: Gathering Your Data
The first step in creating a Sankey chart is to gather your data. This data should be related to the flow of goods, services, or information between different entities. The data should include the source, the destination, and the flow volume for each step in the flow.
Step 2: Choosing a Chart Type
Once you have gathered your data, the next step is to choose a chart type. Sankey charts are available in a variety of chart types, including flowcharts, network diagrams, and Gantt charts. Choose the chart type that best represents the flow you are trying to visualize.
Step 3: Creating the Chart
Once you have chosen a chart type, it is time to create the chart. This can be done using a variety of software programs, including Microsoft Excel, Google Sheets, and Visio.
To create a Sankey chart in Excel, follow these steps:
- Enter your data into a spreadsheet.
- Click on the Insert tab in the ribbon.
- Click on the Sankey chart icon.
- Select the chart type and style you want to use.
- Customize the chart as needed, such as adding filters or changing the chart title.
Step 4: Analyzing the Chart
Once you have created your Sankey chart, it is time to analyze the chart. Look for patterns in the flow of goods, services, or information, and identify any bottlenecks or areas for improvement.
One common mistake when creating Sankey charts is to focus too much on the individual entities and not enough on the flow between them. Remember to zoom out and take a holistic view of the flow, and look for opportunities to optimize and improve the flow as a whole.
Step 5: Sharing Your Chart
Once you have analyzed your Sankey chart, it is time to share the chart with others. This can be done in a variety of ways, including by printing the chart, sharing it as an image file, or embedding the chart in a report or document.
Conclusion
Sankey charts are a useful tool for visualizing the flow of goods, services, or information between different entities. By following these steps, you can learn how to create Sankey charts, use them effectively for data analysis, and share your findings with others.
With a Sankey chart, you can easily see the flow of goods, services, or information between different entities and identify areas for improvement. By understanding the flow, you can make more informed decisions about how to optimize and improve the flow as a whole. Sankey charts are an essential tool for anyone who needs to understand and visualize complex data flows.
