Sankey charts are a powerful tool for visualizing information flow and demonstrating the flow of materials through a process or system. They are particularly useful in demonstrating complex processes or systems where multiple materials or tasks are involved. In this article, we will explore how to create a Sankey chart and its applications.
What Are Sankey Charts?
A Sankey chart is a pictorial representation of the flow of information or material through a network. It is a type of diagram that uses a type of flow chart called a sankey diagram. Sankey diagrams provide a visual representation of the movements of resources that traverse several paths and stages.
Sankey charts are useful for identifying key flow paths and showing dependencies between various elements. They provide a clear and concise overview of the information flow and can be used in almost any field that requires a visual representation of information flow, such as in the healthcare industry, manufacturing, energy, and logistics.
How to Create a Sankey Chart
Creating a Sankey chart is a simple process that involves following a few basic steps:
1. Identify the items or phases that make up the flow of information or material.
2. Determine the flow path for each item or phase and indicate the direction of movement.
3. Assign values to each item or phase and represent them with arrows or lines.
4. Draw the lines between the nodes indicating the direction of the flow.
5. Add text to the chart to explain the information flow and connections between different elements.
Using Sankey Charts in Application
Sankey charts can be applied in various fields and industries where it is important to show the flow of information or materials through a network. Below are some of the applications of Sankey charts:
1. Healthcare: Information flow is crucial in the healthcare industry. Sankey charts can be used to visualize the flow of patients and medical staff through the hospital.
2. Manufacturing: In manufacturing, materials are moved through the production process to be used or transformed into products. Sankey charts can be used to visualize the movement of materials and demonstrate the flow of information.
3. Energy: Sankey charts can be used to visualize the flow of energy through power plants, pipelines, and transmission lines. It can help show the dependencies and flow paths of different components or phases.
4. Logistics: Sankey charts can be used to visualize the flow of material between organizations. It provides a clear and concise overview of logistics systems and can help identify areas for improvement.
Conclusion
Sankey charts are a powerful tool for visualizing information flow and demonstrating the flow of materials through a process or system. They are particularly useful in industries where it is important to show the movement of information or materials through a network. By using Sankey charts, one can easily identify key flow paths and demonstrate dependencies between various elements. Sankey charts have application in a variety of fields, making them an essential tool for anyone involved in identifying key flow paths or dependencies.
