Sankey charts are a powerful tool for visualizing complex systems, workflows, and data flows. These charts help to reveal the relationships between different entities, processes, and data points. In this article, we will dive deeper into the world of Sankey charts and explore the art of visual communication they provide in flow diagrams.
What are Sankey Charts?
Sankey charts are a type of flowchart that uses the concept of flow lines (or streams) to illustrate the paths of different flows. These flows can include physical as well as non-physical entities. They are named after the British mathematician Leonard Sankey, who developed the concept of flow rates.
How are Sankey Charts Created?
The first step to creating a Sankey chart involves sketching the basic structure of the flow diagram. This involves defining the flow lines (or streams) and their direction. In a Sankey chart, the direction of the flow lines is crucial as it determines the flow of the overall system. Additionally, it is essential to map the entities involved in the system accurately.
Once the basic structure is established, the next step is to add flow elements to the diagram. This includes both physical and non-physical entities. Physical entities can be represented by lines, while non-physical entities can be represented by arrows. The flow velocity of each flow can be calculated and added to the chart.
Applications of Sankey Charts
Sankey charts are widely used in various fields, including sciences, engineering, and business. In these fields, they are commonly used to visualize complex systems, workflows, and data flows. For instance, in science, they are used to visualize the reactions and chemical interactions in a system. In engineering, they are used to visualize the flow of water, heat, and gas through a system. And in business, they are used to visualize the flow of financial transactions, process flows, and supply chains.
Benefits of Sankey Charts
There are several benefits of using a Sankey chart over other types of flowcharts. One of the key benefits is that it provides a visual representation of the overall system and its flow. It also enables the visualization of the flow of information and data through the system. Additionally, Sankey charts provide a clear understanding of the relationship between different flows and help in uncovering patterns and trends.
Conclusion
In conclusion, Sankey charts are a powerful tool for visualizing complex systems, workflows, and data flows. They help to reveal the relationships between different entities, processes, and data points. Through the use of the Sankey chart creation and application process, one can gain a deeper understanding of the data being collected. By mastering the art of visual communication through Sankey charts, one can unlock the power of flow diagrams to reveal new insights and opportunities for improvement in any field.
