Sankey charts are a powerful visual tool for understanding complex data by creating a network diagram of supply and demand. These charts are often used in fields such as economics, engineering, and public health and have become increasingly popular in recent years as they provide a clear and concise way to display the relationships between variables. In this article, we will explore what a sankey chart is, how it works, and its applications in various fields.
A sankey chart is a network diagram that visually represents the flow of different variables from sources to sinks, with the flow of data represented as arrows and the relationships between nodes (variables) represented as lines. The resulting chart is useful for analyzing and understanding the interaction between different variables. Sankey charts were first introduced by Peter V. R. Schröder in 1953 to analyze the supply and demand of coal and oil in the UK, but they have since been used in numerous other fields throughout the world.
Sankey charts can be used to visualize a wide range of data, including economic indicators, traffic flow, and environmental data. In the field of economics, sankey charts can be used to analyze supply and demand, analyze economic relationships between countries, and understand the impact of trade policies. In the field of engineering, sankey charts can be used to visualize flow patterns in hydraulic systems and pipelines. In public health, sankey charts can be used to track the spread of infectious diseases, understand the flow of information, and assess the impact of public health interventions.
The process of creating a sankey chart starts with the selection of data and the visualization software used to create the chart. Once the data has been collected, the first step is to organize it into categories or variables, which will be represented as nodes on the sankey chart. Next, you need to establish the flow of supply and demand, using arrows to represent the direction of the flow. Nodes should also be labeled with the name or description of the variable they represent, and edges should be named and annotated with the values of the variables that they refer to.
Sankey charts can be used in a variety of ways to help you understand complex data. For example, you can use sankey charts to visualize the supply and demand for a product, which can help you understand the impact of supply chain disruptions on the prices of goods. You can also use sankey charts to visualize the flow of information in a group or organization, which can help you understand the roles and relationships within the group. Sankey charts can also help you understand the impact of public health interventions by showing the flow of information and resources between different groups.
In conclusion, sankey charts are a powerful and versatile tool for visualizing complex data and understanding the relationships between variables. They can be used in a variety of fields such as economics, engineering, and public health and have become increasingly popular in recent years as they provide a clear and concise way to display the relationships between variables. Whether you work in a small office or a large organization, sankey charts can help you visualize your data in a way that allows you to understand its importance and significance. So, get creative with your sankey charts and see where they will take you!
