Pumping Up Your Sankey Charts: Maximizing Information Sharing and Collaboration

Sankey charts are a powerful visualization tool that can help organizations maximize information sharing and collaboration. By showing the flow of data and resources between different entities, Sankey charts make it easy to identify bottlenecks, improve efficiency, and optimize decision-making. In this article, we’ll explore the basics of Sankey chart creation and applications, as well as tips for enhancing your charts for greater impact.

What is a Sankey Chart?

Sankey charts are named after their creator, Helmut Sankey, and are used to represent the flow of goods, services, or other economic activities between different regions, countries, or entities. They are particularly useful for showing the movement of data and information across different organizations or departments.

Sankey charts have a circular shape, and the flow of data or resources is represented by arrows that connect nodes (entities) in a circular layout. The length of the arrows can represent the volume or value of the flow. The flow can be clockwise or counterclockwise, depending on the direction of the arrows.

How to Create a Sankey Chart

There are several tools available for creating Sankey charts, including Excel, PowerPoint, Tableau, and Python libraries like Sankey and NetworkX. Here is a step-by-step guide for creating a Sankey chart in Excel:

1. Import the data into Excel. You can use a spreadsheet or a data source like a CSV file.
2. Create a pivot table. Select the data range, choose PivotTable & Goal, and choose Sankey.
3. Customize the chart settings. You can choose the layout, colors, and other options to make the chart more useful for your needs.
4. Save and edit the chart as needed.

Tips for Enhancing Sankey Charts

1. Add a legend: A legend can help viewers understand the symbols and colors used in the chart. Include a key or explanation of the chart’s key components.
2. Use meaningful names for the nodes: Choose clear and descriptive names for each node to make it easy to understand the flow of data or resources.
3. Use annotations: Annotations can provide additional information about the chart, such as the date, location, or purpose.
4. Highlight bottlenecks: Identify and highlight areas where data or resources are flowing slowly or inefficiently to draw attention to potential problems.
5. Use conditional formatting: Use conditional formatting to highlight specific types of data or events, such as a high volume of traffic or an increase in data usage over time.

Sankey charts are an effective way to visualize data and resource flow, making it easy to identify bottlenecks and optimize decision-making. By following these tips, you can create compelling Sankey charts that maximize information sharing and collaboration within your organization.
