Sankey charts are a powerful visualization tool used in data analysis and process mapping to show how different parts of a system work together and how they interact. They are particularly useful for showing flow and relationships between different elements in a system, such as product supply chains, supply and demand chains, or information flows through an organization.

In this article, we will take a look at the basic principles behind creating and using sankey charts, as well as some common applications for them. We will also provide tips and tricks for making your charts more effective at conveying information and presenting data.

What is a Sankey Chart?
Sankey charts are graphs that represent the flow of information, resources, or elements through a system. They are made up of multiple nodes (these are typically represented by squares or circles) and lines that connect them, often with specific colors to signify different types of flow.

Nodes can represent different types of resources or elements being transferred, such as components in a supply chain, or a group of employees in an organization. The lines between nodes represent the direction and amount of flow.
Sankey charts are useful for understanding how different parts of a system are interconnected and for mapping out the flow of information and resources through a system. They can also be used to illustrate the flow of data through an organization, such as in an executive summary or a dashboard for stakeholders.

How to Create a Sankey Chart
Creating a sankey chart can be done using a basic template or using a software tool. Here are the steps for creating a sankey chart using a template:

• Select a software tool such as Tableau, Gephi, or D3.js (Data-Driven Documents).
• Choose a template and customize it to your needs, adding nodes and lines as appropriate.
• Save your chart as a file or export it from the software.

A sample sankey chart created using Gephi can be seen in the following image:

Note that the colors and labels may not always show up correctly when using an online graphic, so always create your chart using a software tool if possible.

Common Applications of Sankey Charts
Sankey charts can be used in various fields to present complex data. Here are some common applications:

1. Information flow: Sankey charts can be used to visualize the flow of information through an organization or system. This can be used to show communication flows, feedback loops, or the movement of knowledge or information throughout a process.
2. Supply chain management: Sankey charts can be used to show the flow of goods and resources in an organization. This can be done for a variety of purposes, such as determining the efficiency of a supply chain, identifying bottlenecks, or optimizing inventory levels.
3. Logistics management: Sankey charts can be used to visualize the flow of transportation and logistics systems, such as in a transportation network or a supply chain.
4. Human resource management: Sankey charts can be used to visualize the flow of people within an organization, such as in a hierarchy, team structure, or project management.

Tips and Tricks for Using Sankey Charts
Creating a effective sankey chart depends on several factors, such as the complexity of the data, the intended audience, and the level of detail required. Here are some tips and tricks for using sankey charts effectively:

1. Keep it simple: Sankey charts are designed to show the flow of information, resources, or elements through a system. Avoid overstuffing the chart with too many elements or layers of detail. Focus on the most important information and keep the rest simple and clear.
2. Use colors and labels: The colors and labels can help to illustrate the flow of information, resources, or elements through a system. Use bright, contrasting colors and clear, legible labels to make your sankey chart easy to read and understand.
3. Add context and interpretation: When using sankey charts, it is important to add context and interpretation to help your audience understand what the chart is representing.
4. Customize and personalise: Sankey charts can be customized and personalised to fit the needs of your audience. This can involve adding your own design touches, colors, and data, or altering the layout or scale of the chart to suit the purpose.

In conclusion, sankey charts are a powerful visual tool for presenting complex data and showing how different elements work together. By understanding the basic principles behind creating and using sankey charts, as well as common applications, you can use them to understand and communicate with a wide range of stakeholders. Remember to keep the information simple, use colors and labels effectively, and add context and interpretation to make your sankey chart clear and easy to understand.
