Introduction:
A Sankey chart is a type of flowchart that is used to represent the flow of materials, energy, and information in a system. It was originally developed in the 19th century by an engineer named William Edward Sankey. Sankey charts have been used for a variety of purposes, including process mapping, resource allocation, and environmental analysis. In this article, we will explore the basics of Sankey chart creation and some examples of how they can be used to streamline processes and improve data visualization.

Sankey Chart Creation:
There are a variety of software programs that can be used to create Sankey charts, including Microsoft Visio, Lucidchart, and Gliffy. These programs allow users to create a Sankey chart by drawing nodes and links between them. Users can also specify the type of flow that is being depicted, such as material flow or information flow.

Once the nodes and links are added to the chart, users can customize the appearance of the chart, such as the color and shape of the nodes and the thickness of the links. Users can also add labels and annotations to the chart to provide additional information.

Applications of Sankey Charts:
Sankey charts can be used in a variety of industries and applications, including manufacturing, logistics, and environmental analysis. In manufacturing, Sankey charts can be used to visualize the movement of raw materials through the production process. In logistics, they can be used to track the flow of goods between different locations. In environmental analysis, they can be used to visualize the flow of pollutants through an ecosystem.

Streamlining Processes with Sankey Charts:
Sankey charts can be used to identify inefficiencies and bottlenecks in a process and provide insights into how to optimize the flow of materials, energy, or information. For example, a manufacturer might use a Sankey chart to analyze the flow of raw materials through the production process and identify areas where material is being wasted or where production times can be improved.

In summary, Sankey charts are a useful tool for visualizing and understanding the flow of materials, energy, or information in a system. They can be used to create a variety of flowcharts, including process maps, resource allocation charts, and environmental flow charts. By identifying inefficiencies and bottlenecks, Sankey charts can help streamline processes and improve data visualization.
