Sankey charts, also known as a stream or flow diagram, are a data visualization tool that is ideal for creating a narrative with different elements and flow. Sankey charts are easy to create and interpret, and they can help people make sense of large volumes of data in a concise manner. In this article, we will explore the power of a Sankey chart and the many ways they can be used to transform data visualization into insightful storytelling.
Introduction
A Sankey chart is a visual representation of flow or an interaction between different entities. It consists of pipes that represent the different entities that are moving along the path. Each pipe is labeled with the values of the entities associated with the pipe. The flow of data is represented by the pipes, and the interaction between them is represented by the values of the entities that make up the pipes.
Sankey charts are commonly used in various fields, such as economics, engineering, social sciences, computer science, and more. In this article, we will explore the power of a Sankey chart, the importance of interpreting the different elements of the chart, and the ways in which they can be used to transform data visualization into insightful storytelling.
The Power of Sankey Charts
Sankey charts have many advantages over traditional charts, such as line graphs, bar charts, and pie charts. Here are some of the advantages of using a Sankey chart to visualize data:
– The ability to show different elements of the data in a concise manner.
– The use of different colors and line types makes it easy to identify the source and destination of the data.
– The flow graph representation of the data can make it easier to visualize connections between different entities.
– The use of the values for the entities makes it easy to understand the impact of each element on the overall data.
– The use of the Sankey chart makes it easy to add annotations and labels to highlight the different elements of the data.

The Interpretation of Sankey Charts
Once you have created a Sankey chart, the next step is to interpret the different elements of the chart. Here are some guidelines to follow when interpreting a Sankey chart:

• The source node of the pipe represents the origin of the data.
• The target node of the pipe represents the destination of the data.
• The value of the entity on the source node represents the total value of the data.
• The line connecting the source and target nodes represents the total value of the data.
• The value of the entity on the target node represents the value of the data after being processed.
• The arrows connecting the source and target nodes represent the direction of the flow of the data.

Creating a Sankey Chart
A Sankey chart can be created by following the steps below:
1. Understand the data: Look at the data that you want to visualize and make sure that you understand its key elements.
2. Think about the entities: Identify the different entities that need to be represented in the Sankey chart.
3. Analyze the flow patterns: Look for any patterns and trends in the flow of the data.
4. Create the Sankey chart: Use a software or tool to create the Sankey chart.

Usage of Sankey Charts
Sankey charts have many applications, including:

• Sales and Marketing analysis: You can use a Sankey chart to visualize the flow of sales to different regions or markets.
• Supply Chain Analysis: A Sankey chart can help you visualize the flow of materials, components, and products in a supply chain.
• Resource Allocation: A Sankey chart can help you visualize the flow of resources, such as labor, raw materials, and capital, in the business.
• Project Resource Allocation: A Sankey chart can help you visualize the flow of resources, such as labor, raw materials, and capital, in a project.
• Environmental Health Analysis: A Sankey chart can help you represent the interaction of pollutants flowing through the environment and the different sources and sinks.

In conclusion, Sankey charts are a powerful visual tool that can help you understand complex data and make sense of it. By creating a Sankey chart and interpreting the different elements of the chart, you can transform your data visualization into insightful and actionable insights.
