Unleashing the Power of Process: A Guide to Creating Sankey Charts
Sankey charts are a powerful visual tool for showing the flow of materials, energy, or information through a system. Named after their creator, English engineer named Charles Sankey, these charts are widely used in process engineering, environmental science, and other fields to understand and optimize the flow of resources.
In this guide, we will show you how to create Sankey charts using a popular process called the Sankey Method. You will learn how to gather and organize your data, create the basic structure of a Sankey chart, and customize it to your needs.
Gathering and Organizing Your Data
The first step in creating a Sankey chart is to gather and organize your data. This may involve creating a flow diagram, collecting data from experiments or simulations, or using existing data sources.
Once you have your data, it is important to clean and organize it so that it is ready to be used in your Sankey chart. This may involve removing duplicates, filling in missing values, and transforming data into the appropriate format.
Creating the Basic Structure of a Sankey Chart
Once your data is organized, you can start creating your Sankey chart. This typically involves creating a flow diagram that shows the flow of materials, energy, or information through your system.
To create the basic structure of a Sankey chart, you will need to:
- Identify the source and sink of your system.
- Determine the direction of the flow in your system.
- Create nodes for each process or step in your system.
- Connect the nodes with arrows to show the direction and rate of flow.
Once you have your basic structure in place, you can begin adding details and customizing your chart to better reflect the needs of your system.
Customizing Your Sankey Chart
There are many ways you can customize your Sankey chart to better reflect the needs of your system. Some common options include:
- Adding labels and annotations to your chart.
- Changing the color or style of your arrows to make them more easily understandable.
- Adding filters or overlays to show different aspects of your system.
- Adding interactivity to your chart so that you can explore different parts of your system in more detail.
Conclusion
Sankey charts are a powerful tool for visualizing the flow of materials, energy, or information through a system. By following the steps in this guide, you can create a Sankey chart that accurately reflects the dynamics of your system and provides valuable insights for process optimization and resource management.
Remember that the best way to create Sankey chart is by practice and so it’s always suggested to work on small scale projects first before jumping into large projects.
