If you've worked with data before, you'd know that data is easier to understand when it's visual.
For example, with flow diagrams, you can show how information or resources move from different stages of your industry's typical processes. Among these flow diagrams, the Sankey diagram stands out because it shows changes in flow size.
Knowing the Sankey diagram is one thing, though. The problem is that building one manually can be challenging and time-consuming. So, you'll need a dedicated tool to make it like Wondershare EdrawMax. In this article, you'll learn how to create a Sankey diagram with the help of this tool.

What Is a Sankey Diagram and Why Use One?
A Sankey diagram is not used much in regular human life. However, in highly technical fields, you'll see them. Thus, if you're working in any of these fields, you've probably encountered a Sankey diagram before without even realizing it. These flow-based charts are often used in presentations because they allow the presenter to show how specific resources move across the different stages.

The width of each flow (otherwise known as the "link") is proportional to the amount it represents. They also connect to nodes that represent stages of the process. This is, more or less, the essence of what makes up a Sankey diagram.
Uses of Sankey Diagrams
Sankey diagrams often track energy usage, budgets, website traffic, or customer journeys. For example, you might see one showing how total revenue splits into different departments, or how website visitors drop off at each step of a signup funnel. Because the data is visualized as flows, it's much easier to understand than rows of numbers in a spreadsheet.
Benefits of Sankey Diagrams
The main benefit of a Sankey diagram is clarity. You can immediately spot where resources are concentrated, where losses occur, or which outcomes dominate. They also make comparisons easier because the width of each link tells the story quickly. Makes Sankey diagrams one of the most effective tools for explaining how data moves through a system.

Bonus: Common Mistakes To Avoid When Making a Sankey Diagram
Here are some common mistakes that beginners in Sankey diagramming commit. Don't worry, there's no wrong way to diagram (so long as it works for your team), but here are some general rules of thumb you can follow as you learn the art. After all, a diagram is also meant to be consumed by other people.
While these are tailor-fitted for Sankey diagrams, you can apply them to flowcharts or similar diagrams. Here they are:
- Overloading the diagram. Including every minor stage or data point can make the diagram overwhelming. Group smaller items together or focus only on the key stages. For example, when showing energy consumption, combine minor appliances into one category instead of listing each separately.
- Using inconsistent flow directions. Flows should consistently move in the same direction (e.g., left to right or top to bottom). Mixing directions forces viewers to reorient themselves, making the diagram harder to follow constantly.
- Using similar colors for every flow. If all the links look the same, readers will struggle to distinguish them. Use contrasting colors to highlight different categories or data sources.
- Forgetting to scale the flow widths proportionally. Link widths must match their data values. If scaling is off, the diagram becomes misleading. Always double-check your data before finalizing the diagram.
- Forgetting to label nodes or flow links. Labels help readers understand exactly what each node and link represents. Place labels close to the relevant paths and keep the text concise for easy scanning.
