Sankey charts are a visual representation of data flow that can be used to break down complex data sets into useful insights. They can be used in a variety of industries and applications, and they offer a unique way to analyze and visualize data.
Sankey charts have been around for over 150 years, but they are not widely used, and there is a lack of understanding about their capabilities. In this article, we will explore the use of Sankey charts and their potential applications in a more comprehensive view of data flow.
What is a Sankey Chart?
Sankey charts are a type of diagram that can be used to represent data flow in a more concise and readable way. They are similar to network diagrams, but their elements are more intuitive and easier to understand. They consist of a flow line for each stream of data, often with a color coded to represent the direction of the data flow.
Sankey charts are useful when you need to have a better understanding of how different data streams interact and impact each other. This is particularly useful in industries such as finance, logistics, and manufacturing, where data flow is crucial.
Sankey charts work by creating a visual representation of data flow, and this can be done at a variety of scales, including large datasets, medium-sized data sets, and small data sets.
How to Create a Sankey Chart
Creating a Sankey chart involves a few steps. The first step is to define the data you want to visualize, and the second step is to create the flow lines.
The first step involves outlining the data you want to visualize. This needs to be done in a way that allows you to identify the different streams of data. Commonly used data fields include time, location, type, weight, or value. After identifying the data fields, you need to assign a flow line for each field.
Once you’ve defined the data and created the flow lines, the next step is to order the flow lines. This can be done by placing the flow lines in a logical order that represents the direction of data flow. This is particularly useful when you want to show how different data streams impact each other.
The final step is to add colors to the flow lines. The colors can signify how the data flow is organized, such as high traffic flow being represented by blue, medium flow is represented by yellow, and low traffic flow is represented by green.
Why Use Sankey Charts?
Sankey charts offer a unique way of visualizing data flow, making it easier to understand complex data sets. They are also able to show data flow at multiple scales, making them useful for industries such as finance, logistics, and manufacturing.
Sankey charts also offer an intuitive way for people to understand the data flow, making it easier to spot patterns and trends that might not be immediately obvious. They are also useful when you need to compare data sets, as they allow you to visualize the impact of different data streams on each other.
Conclusion
Sankey charts are a powerful tool for analyzing and visualizing data flow. They offer a unique way of breaking down complex data sets into useful insights, making it easier to spot patterns, trends, and compare data sets. When used properly, they can provide valuable insights and help you make better decisions.
