Sankey charts, also known as flow diagrams, are a type of diagram that illustrates different types of flow or circulation, such as money, information, or processes. They are commonly used in fields such as economics, engineering, and social sciences to visualize complex systems and flows within those systems.
Sankey charts come in several formats, including bar charts, line charts, and stacked bar charts. However, Sankey charts are known for their unique feature of showing multiple types of flow at the same time, including information, money, and process flows, as well as other types of circulation. These charts are excellent tools for understanding and analyzing complex systems and flows.
To create a Sankey chart, you simply need to identify the different types of flow you want to visualize and determine the values of each type of flow. You can then connect each flow with a line or bar, and label each flow type with a number or letter to distinguish them. You can also add labels and arrows to help guide the reader’s attention and explain the flow.
There are several reasons why Sankey charts are an effective visualization tool. One reason is that they emphasize the importance of flow, which is often the most neglected aspect of complex systems. By using Sankey charts, you can help highlight which types of flows are more important, and which types of flows may need to be addressed or managed differently.
In addition to emphasizing flow, Sankey charts can be used to uncover patterns and connections by showing how different types of flows are related to each other. This can help show how different areas are interconnected and how changes in one area can affect other areas. For example, a Sankey chart can be used to show the flow of money from one source to another, including how this flow affects the output of a production process or the flow of information from one department to another.
Another reason why Sankey charts are effective is that they are easily understood by both technical and non-technical people. This is because Sankey charts are simple to understand, even for people who are not familiar with flow diagrams. They also provide a visual representation of flow that is easy to interpret, which can help identify potential problems and opportunities for improvement.
There are several tools available for creating Sankey charts, including software programs such as Microsoft Excel or Google Sheets, and online tools such as Canva and Piktochart. These tools allow you to create sophisticated and detailed Sankey charts, but they can also be basic and unappealing. If you want to create a more polished Sankey chart, you may need to use software or online tools designed specifically for creating flowcharts or diagrams.
Finally, it’s important to remember that Sankey charts are a tool, not a replacement for hard data or analysis. They should be used as a tool for visualization and analysis, and not to make decisions based solely on them. Sankey charts are good for showing trends and patterns, but they should not be used to replace hard data or analysis.
In conclusion, Sankey charts are a powerful tool for understanding and analyzing complex systems and flows. They are easy to use, yet effective at highlighting important flow cycles and patterns, and can help identify potential problems and opportunities for improvement. With a bit of creativity and attention to detail, Sankey charts can be a valuable addition to any analysis or visualization project.
