Sankey charts are a powerful tool for visualizing complex relationships between processes and components. These charts are used in a wide range of applications, from supply chain management to manufacturing to environmental science. In this article, we will explore how to create and use sankey charts, including steps for gathering data and selecting the right type of chart. We will also discuss the key features of sankey charts and how they can be used to understand relationships between complex systems.
Gathering Data
The first step in creating a sankey chart is to gather the relevant data. This data should be organized in a way that makes sense for the specific use case it will be applied to. The data should be organized into categories and subcategories, and each category should represent a different process or component.
For example, in a supply chain management scenario, the data would include the different suppliers, the components supplied to each supplier, and the final products. These components could be grouped into categories such as raw materials, intermediate products, and assembled parts, and each category could be represented in a sankey chart.
Sankey Chart Creation
Once you have gathered the data, you can begin to create a sankey chart. The first step is to select the appropriate type of sankey chart. Sankey charts can be created in a variety of ways, including stack, pipe, and tree. Stack and pipe sankey charts are typically used for visualizing relationships between categories and subcategories, whereas tree sankey charts are more commonly used for visualizing hierarchical relationships.
In the step-wise design of the sankey chart, determine how many layers or branches you want and how each branch will be labeled. Each division in the chart will represent a different process or component, and the labels in it should clearly describe the relationship between the processes and components.
Customizing Sankey Charts
Once the sankey chart has been created, you can customize it to better understand the relationships between the processes and components. For example, you can add markers or shapes to highlight important or significant points, or you can use arrows to show the direction of flow.
You can also add labels to each branch to provide more detail about the relationship between the processes and components. For example, you could label the branches with the name of each process or component, the flow direction, and the type of flow.
Key Features of Sankey Charts
Sankey charts have several key features that make them powerful tools in visualizing relationships between processes and components. First, they allow you to identify the relationships between different processes and components, which can help you identify opportunities for optimization or improvement.
In addition, sankey charts have the ability to create a high degree of transparency and clarity, allowing you to easily see the flow of data and identify bottlenecks or areas for improvement.
Sankey charts can also be used in various ways, from simple to complex, and they can be adjusted to better suit the specific needs of your organization.
Conclusion
Sankey charts are a powerful tool for visualizing complex relationships between processes and components. By gathering the relevant data and organizing it carefully, you can create a sankey chart that clearly and accurately depicts the flow of data between different processes and components. With customization options and key features, these charts can help you understand relationships between processes and components in ways that would otherwise be impossible.
