An introduction to Sankey Charts
Sankey charts, also known as network diagrams, are a type of chart used to visualize causal relationships between different elements in a system. When it comes to complex data, a Sankey chart can be a very effective tool, as it allows you to visualize the flow of information or materials through a network of entities.
To understand how Sankey charts work, you need to understand the basic structure of a Sankey chart. A Sankey chart typically consists of three main components: a source node that represents the starting point, a set of intermediate nodes that represent the flow of information or materials between the nodes, and a sink node that represents the end point.
To create a Sankey chart, you start by identifying the nodes and their corresponding inputs and outputs. Then, you use a connection diagram to represent the flow of data or information between the nodes. It is worth noting that Sankey charts can also be used to represent other types of flow, such as chemicals or materials, or any other substance that can be passed between nodes.
The process of creating a Sankey chart can be quite complex, but once you understand the basic structure, the process can be relatively straightforward. One way to create a Sankey chart is by using a flow diagram, which is a graphical representation of a system of flowing objects and substances. The flow diagram includes the flow lines that represent the movement of material or information from one node to another.
Once you have your flow diagram, you can use a Sankey chart software to transform it into a visually appealing Sankey chart. Many data visualization software allow you to convert your flow diagram into a Sankey chart, and then add additional elements to make it more informative such as labels for the nodes, flow direction, and color coding for the material or information.
Applications of Sankey charts in daily life
Sankey charts are not limited to academia, and you can find them in everyday life too. For instance, in transportation engineering, Sankey charts can be used to analyze the flow of people and vehicles between different locations. The chart shows the number of people and vehicles entering and leaving each location, and how they are distributed across the network.
Another application of Sankey charts is in the field of medicine. Sankey charts can be used to identify the flow of drugs between patients, hospitals, and other healthcare facilities, and where potential bottlenecks or delays may occur during drug distribution.
In the finance industry, Sankey charts can be used to identify the flow of transactions between different financial institutions or individuals, or to visualize the movement of assets such as stocks or currencies.
Conclusion
Sankey charts are a valuable tool for exploring complex data, particularly when it comes to analyzing causal relationships between various entities in a network. By understanding the basic structure of a Sankey chart, you can effectively create and apply it to different fields such as transportation engineering, medicine, and finance, to name a few. Whether you are an analyst, researcher, or data scientist, understanding the importance and application of Sankey charts can help you gain a deeper understanding of your data and improve efficiency and effectiveness in analyzing your work.
