In the vast field of visual communication, visual graphics hold a powerful significance. They have been used to depict data, communicate a message, and influence perspectives. Sankey chart, a type of diagram used to depict the flow of information, is no different.
A sankey chart, also known as a flowchart, is a two-way flowchart that links the input point to the output point and visualizes the information flow. This chart is widely used in fields such as project management, organizational structure analysis, and process analysis.
Sankey charts are created using the principle of flow, where input and output points represent the beginning and end of the flow. The key components of a sankey chart include the input and output points, the directions of flow, and the sizes of the components to represent the magnitude of the flow.
To create a sankey chart, one needs to determine the components of the information flow, starting with the input point, or source, where the flow begins. These components are typically categorized and labeled for ease of understanding. Next, the output point, or sink, where the flow ends, is identified. Lastly, the direction of the flow is determined, with the arrow pointing in the direction of the flow.
Once the components are identified, the sizes of the components, or arrows, representing the flow, are determined. The size of the component is proportional to the magnitude of the flow. This is done by considering the magnitude of the flow, such as the number of components, the length of the line, and the color of the lines, to convey the flow.
Sankey charts are often used in visualizing complex processes, such as project management, where they can help to provide clarity and understanding of the various components. They are also useful in organizational structure analysis, where they can help to identify the flow of information within an organization. Additionally, in process analysis, they can help to visualize the flow of information in a specific process, making it easier to understand the flow of information.
However, one of the benefits of sankey charts is that they are easy to create, even for those who are not necessarily experts in data visualization. Sankey charts can be created using a variety of tools, including computer software such as Microsoft Excel, Adobe Illustrator, and VLOOK-Up, as well as specialized software from specialized vendors.
Sankey charts also offer many benefits. They are a cost-effective way of communicating complex information, as they can be created at a lower cost compared to other types of visual graphics. They are also interactive, allowing the viewer to change the direction of the flow, which can be useful in understanding the flow of information. Additionally, sankey charts are scalable, meaning that they can be used to visualize the flow of information at any level of analysis.
In conclusion, sankey charts are a tool that can be used to depict visual information flow in complex processes. From project management to organizational structure analysis, sankey charts offer a powerful tool for understanding and analyzing the flow of information. With their ease of use and interactive features, they can make it easier to visualize and communicate complex information.
