Unleashing the Power of Sankey Charts: Visualizing Data Flow and Identifying Trends
Sankey charts are a powerful data visualization tool that allow you to see the flow of data in a given system and identify trends and patterns. These charts were originally developed by Charles Sankey in the mid-19th century and have since been used in a variety of applications, including process flow analysis, supply chain management, and financial analysis.
How to Create a Sankey Chart
To create a Sankey chart, you need to follow these steps:
- Gather the data
The first step in creating a Sankey chart is to gather the data that you want to visualize. This data should represent the flow of a particular system or process. - Choose the data visualization tool
There are several tools available for creating Sankey charts, including Microsoft Excel, Google Sheets, and online data visualization software such as Sankey Flowchart. - Build the flowchart
Start by creating a flowchart that represents the flow of the data in the system or process. This flowchart should show the inputs, outputs, and intermediate steps of the process. - Assign sankey diagrams
Once you have created the flowchart, it is time to assign sankey diagrams to each input, output, or intermediate step. Sankey diagrams are arrows that represent the direction and magnitude of the flow of data. - Customize the chart
Finally, you can customize the chart to your liking, including choosing colors, fonts, and other visual elements.
Applications of Sankey Charts
Sankey charts are useful in a variety of applications, including:
- Process flow analysis: Sankey charts are often used to analyze the flow of a process and identify bottlenecks and areas for improvement.
- Supply chain management: Sankey charts can be used to visualize the flow of goods and services through a supply chain, helping to identify areas where costs can be reduced and efficiency can be improved.
- Financial analysis: Sankey charts can be used to visualize the flow of financial data, such as the flow of cash or the flow of profits.
- Environmental analysis: Sankey charts can be used to visualize the flow of pollutants or the flow of energy through a particular system.
Using Sankey Charts to Identify Trends and Patterns
One of the benefits of using Sankey charts is the ability to identify trends and patterns in the flow of data. By analyzing the flow of data over time, you can identify changes and trends that may be occurring in the system or process.
Conclusion
Sankey charts are a powerful data visualization tool that can be used to visualize the flow of data in a given system and identify trends and patterns. These charts are easy to create and use and are applicable to a variety of fields, including process flow analysis, supply chain management, financial analysis, and environmental analysis.
