The Sankey chart is a powerful tool for visualizing complex data that is difficult to express through traditional bar or line charts. It is a reliable method for creating visualizations that convey hierarchical relationships between different entities, and it is well-suited to representing the flow of substances, resources, or events in a flowchart. This article will explore how to create Sankey charts and showcase some examples of their practical applications for visualizing complex data.
Sankey charts are created by graphically representing a flow of data or information, with each node representing a source, sink, or intermediate point in the flow, and each link representing the direction and flow of the data or information. This can be applied to a wide range of data sets, such as inventory levels, production flow, trade flows, and more.
To make an effective Sankey chart, it is important to have a clear understanding of the flow of data that you want to represent. The chart can be designed with a central axis representing the origin point of the flow, and each node can be labeled with a caption that describes the nature of the flow and the quantity associated with the node. The connection lines between nodes can then be used to visually represent the flow of the data.
Sankey charts can be a great tool for demonstrating hierarchical relationships in a data set, which is especially useful for fields such as finance, economics, and social sciences. They can also be used to illustrate the direction and flow of data in a data set, making it easy to understand the flow of inventory levels or the flow of products through a logistics network.
An example of a Sankey chart that can be useful for illustrating the flow of information in a professional organization is the following:
+-------------------------+
| Employee (Source and Node) |
+-------------------------+
| A (Employee) |
+-------------------------+
| | Employee B (Sink) |
+-------------------------+
| Earnings |
+-------------------------+
In this example, the Sankey chart shows the flow of employee earnings. The top node represents the source of an employee (an employee), and the bottom node represents the sink (earnings). The vertical links between the nodes indicate the direction of the flow, while the numerical values on the nodes indicate the quantity of the flow associated with each source.
Sankey charts have many practical applications in various fields, including social sciences, economics, finance, logistics, and more. They can be used to examine complex systems and relationships, and to draw attention to key points and critical transitions along a flow. They have become a powerful tool for visualizing and communicating data in a visual and concise way, making it easier to understand complex data sets and highlight important trends and insights.
In conclusion, Sankey charts are a valuable tool for visualizing complex data, and they can be an efficient and effective way of representing hierarchical relationships, flows, and directions. Whether you’re analyzing inventory levels, product flow, or trade flows, a Sankey chart can reveal patterns and relationships in a clear, concise, and effective manner. With careful design and thoughtful placement of connections, Sankey charts can be used to effectively communicate important data and insights, making them a valuable asset in visualizing complex data.
