Sankey charts are a type of chart that can be used to visually represent complex data relationships. They are commonly used in fields such as finance, engineering, and social sciences. In this article, we will explore how sankey charts can help you unlock complex data and provide a visual guide on their creation and application.
What are Sankey Charts?
Sankey charts are a type of network graph that represents a relationship between two variables in a visual way. It is commonly used to represent time-series data over time, but can also be used to represent time-series data over space. The basic concept behind sankey charts is that you can use a series of arrows to represent the flow of data between different sources and sinks.
How do sankey charts work?
A sankey chart typically consists of two vertical axes, representing the flow of data between the two variables. The horizontal axis represents the sources and the vertical axis represents the sinks. Between the two axes, you draw a series of arrows that represent the flow of data. For example, in the diagram below, each row represents a specific source, and each column represents a specific sink.
Types of sankey charts
There are several different types of sankey charts, depending on the specific type of data being represented. Here are a few examples:
- Time series sankey chart: This type of sankey chart is used to represent time-series data over time. For example, you might create a sankey chart to show the flow of data over the course of a product生命周期。
- Spatial sankey chart: This type of sankey chart is used to represent time-series data over an area. For example, you might create a sankey chart to show the flow of data over a geographic region, such as a nation or continent.
- Hierarchical sankey chart: This type of sankey chart is used to represent time-series data that is hierarchical in nature. For example, you might create a sankey chart to show the flow of data as it is organized in a hierarchical structure, such as levels of a supply chain.
Creating sankey charts
Creating a sankey chart can be a straightforward process, but there are a few things to keep in mind to ensure that your chart is effective.
First, ensure that your sources and sinks are clearly defined. This will help you to represent the flow of data effectively.
Second, choose an appropriate scale for the horizontal axis and the vertical axis. This will help you to accurately represent the data being plotted.
Third, use appropriate labels and legends to help your viewers understand the data being plotted.
Application of sankey charts
Sankey charts have a range of applications, both in and outside of finance, engineering, and social sciences. They are often used in fields such as:
- Supply chain analysis: These charts are ideal for displaying the flow of data throughout a supply chain, allowing analysts to visualize the complexity of a supply chain.
- Energy production: These charts can be used to track the flow of energy from generation to distribution.
- Environmental analysis: These charts can be used to display the flow of data related to pollution or waste.
Conclusion
Sankey charts may seem complicated, but they can be a powerful tool for unlocking complex data and understanding the relationships between different variables. Whether you are working in finance, engineering, or social sciences, a sankey chart can help you to create a visual representation of your data that is easy to understand and interpret.
