Introduction

At its core, a sankey chart is a type of visual data representation that shows flow between different components. It is a popular tool used to explore complex network data because it allows for the visualization of the flow of information or resources in a network.
In this article, we will take a look at how to create sankey charts and how they can be used to explore and analyze complex network data. We will also provide some common applications of sankey charts and explore ways to improve and customize them to meet specific needs.
Step 1: Create the Diagram

To create a sankey chart, you will first need to draw the information that you want to visualize. This can be done using software such as Microsoft Excel or specialized graphing software such as Tableau or Power BI. The diagram should include all the relevant information and be drawn accurately so that you can easily see the flow of data or resources.
Step 2: Identify the Components

The next step in creating a sankey chart is to identify the components you want to visualize. These could be people, devices, processes, or any other type of element that contributes to the flow of data or resources in the network.
Step 3: Determine the Flow Direction

Once you have identified the components, you need to determine the flow direction. This is where the sankey chart draws its name from. The flow direction is specified by the direction of the arrows.
Step 4: Label the Components

Labeling the components is important to help visualize the flow of data or resources. Each component should have a label that indicates its function or role in the network.
Step 5: Customize the Diagram

There are many ways to customize a sankey chart, such as adjusting the color scheme, adding annotations, or changing the font. These changes can help make the diagram more easily understandable and help draw attention to key data points.
Applications

There are many different applications for sankey charts, ranging from exploring supply chain management networks to analyzing customer behavior in a retail store.
For example, in the supply chain management field, sankey charts can be used to explore the flow of materials and information between different stages of the supply chain. This can help identify bottlenecks and areas for improvement, as well as identify potential new suppliers or partners.
In the retail industry, sankey charts can be used to explore customer behavior and preferences. This can help retailers better understand their customers and tailor their products and services to meet their needs.
In conclusion, sankey charts are a powerful tool for exploring complex network data. By following these steps, you can create a sankey chart that accurately represents the flow of information or resources in a network and help you better understand it.
