Introduction:
Sankey charts are an effective tool for illustrating complex relationships between datasets. They have become increasingly popular in recent years, especially among analysts, researchers, and business professionals who need to visualize interconnections between different entities or processes. In this article, we will examine what a Sankey chart is, how it can be created and applied, and the benefits it offers.
What is a Sankey Chart?
A Sankey chart is a diagram that represents the flow of information or resources between different entities or processes. It is commonly used to visualize the flow of supply chains, energy flows, transportation networks, and data flows. The basic structure of a Sankey diagram consists of a set of nodes representing the sources and sinks of the flow, and arrows connecting these nodes. Each arrow corresponds to a specific flow, such as a flow of goods or a flow of information.
How to Create a Sankey Chart
Creating a Sankey chart involves a few basic steps:
- Identify the entities or processes you want to visualize
- Assign a category or label to each source or sink (e.g., suppliers, customers, production, etc.)
- Determine the direction of the flow (incoming or outgoing) for each arrow
- Create the arrows and nodes (you can use a software tool like Lucidchart to assist with the visual design)
Applications
Sankey charts are widely used in various fields, including logistics, finance, engineering, and social sciences. Here are some common applications:
- Supply chain analysis: Sankey charts can help visualize the flow of products through different suppliers and distributors, allowing decision-makers to identify bottlenecks and potential problems.
- Energy analysis: Sankey charts can be used to analyze energy flows in industries such as oil and gas, electric, and renewable energy, showing the connections between different sources and destinations of energy.
- Transportation network analysis: Sankey charts can be used to visualize transportation networks, such as highways, flights, and train routes, showing the flow of goods and people.
- Data analysis: Sankey charts can be used to visualize the flow of data between different data sources, aiding in data analysis and understanding data connections between different datasets.
Benefits
Sankey charts offer a number of benefits, including:
- Visualizing complex relationships: Sankey charts allow for the visualization of complex relationships between different entities or processes, making it easier to understand and analyze.
- Simplifying data visualization: Sankey charts are unique in that they break down complex data into a clear, visual format. This makes it easier to understand and identify key relationships and patterns.
- Interactivity: Sankey charts can be interactive, allowing users to explore different flows and connections with the press of a button. This promotes deeper engagement and understanding.
Conclusion
Sankey charts are an excellent tool for visualizing complex relationships between different entities or processes. With an intuitive interface and extensive applications across a variety of fields, they add value to any data visualization project. By leveraging Sankey charts, analysts, researchers, and business professionals can gain a deeper understanding of data and make more informed decisions.
