Introduction

Have you ever felt overwhelmed when trying to understand a complex dataset or organizational structure? Sankey charts can provide a visual representation that makes the information much more legible and easier to understand. In this article, we will explore the basics of creating a Sankey chart, its various applications, and best practices to enhance the effectiveness of your visualization.

Creating a Sankey Chart

A Sankey chart is a type of network graph that is commonly used to visualize interdependencies between entities. The main components of a Sankey chart include the main network, the nodes (entities), and the links (dependencies) that connect them. These elements can be represented in different shapes, colors, and sizes, ensuring that they stand out clearly in the chart.

The most common tools for creating a Sankey chart are Microsoft Excel, Google Sheets, and the Gephi software. Creating a Sankey chart is a simple process that involves entering data into a spreadsheet, drawing the main network using a diagramming tool, and adding links as necessary. There is no need to have extensive knowledge of graphic design, as the software automatically generates a professional-looking chart.

Sankey Charts in Practice

Sankey charts are widely used in business environments and can be applied for many different reasons. Here are some applications of Sankey charts:

1. Organization Structure
   Sankey charts can be used to visualize the organizational structure of a company, department, or team. Each element represents a department, team, division, or employee, while links represent the relationships between them.

2. Supply Chain Analysis
   Sankey charts can be used to analyze the supply chain of a company. The main lines represent the relationships between suppliers and the destination point, while the nodes represent the suppliers and the customer.

3. Resource Consumption Analysis
   Sankey charts can be used to analyze the consumption of resources such as materials, labor, and energy. The main lines represent the consumption of resources, while the nodes represent the producers or facilities that handle these resources.

4. Environmental Impact Analysis
   Sankey charts can be used to visualize environmental impact analysis by connecting the main lines with variables such as carbon emissions, water consumption, and energy usage. This allows for a more comprehensive view of the environmental impact of different operations or services.

5. Project Network Analysis
   Sankey charts can be used to analyze the interdependencies and progress of a project network. Each node represents a project, while the links represent the dependencies between project phases or tasks.

Best Practices

To create a Sankey chart, the following best practices should be followed:

1. Use a large selection of colors to distinguish between different elements such as departments, regions, etc.

2. Ensure that the size and shape of nodes and links are appropriately sized and shaped to represent their importance or frequency of use.

3. If the chart requires multiple scales, create a scale legend or use a different color scheme within the same color palette.

4. Consider using color combinations that are both visually appealing and easy to distinguish.

5. Use labels and legends strategically to make the information more accessible and understandable.

Conclusion

Sankey charts can be powerful visual representations of complex relationships. Whether you are working on a business project, conducting research, analyzing data, or studying a social network, the ability to easily visualize relationships is critical. By following best practices in data visualization, you can create Sankey charts that are clear, accessible, and engaging.
