Sankey charts are a visual representation of data flow and relationships. They can be used in various industries such as engineering, finance, business, and more. In this article, we will explore the secrets of how to create and use Sankey charts, including their applications and advantages.

Sankey charts are a type of diagram used to visualize the flow of data, typically represented by circular paths or lines. The chart shows how an object or action flows through different nodes based on the information provided. Sankey charts can be used to demonstrate the cause-effect relationship between factors and their effect on the outcome.

How to Create a Sample Sankey Chart

Here’s a simple step-by-step guide to creating a sample sankey chart:

1. Gather your data: To create a sankey chart, you need to have a list of relevant data points. This can include numerical values for flow rates, or flow directions.

2. Organize your data: Organize your data by nodes and links. Assign a unique color to each node, and assign each link a unique direction (upward or downward) depending on whether it is flowing from the node to another or the other way around.

3. Create a visual layout: Use a software program to layout the connections between nodes and links. Ensure that the layout is easy to read and interpret.

4. Display the data: Use graphs or charts to display the data to make it easier to understand. This could be in the form of pie charts, bar charts, or line charts.

How to Use Sankey Charts in Different Industries

Sankey charts have applications in various fields. Here are a few examples:

1. Healthcare: In healthcare, an example of a sankey chart could be to explain the flow of data between hospitals and doctors, pharmacies, and medical centers. By using a sankey chart, healthcare providers can visualize the flow of information and make data-based decisions.

2. Finance: In finance, a sankey chart could be used to explain the connection between various financial transactions between investors and companies. By using a sankey chart, financial experts could better understand the data and make informed decisions.

3. Engineering: In engineering, a sankey chart could be used to explain the flow of data between various design elements in a product, such as metals, plastics, and chemical components. By using a sankey chart, engineers could better understand the flow of data and make improvements.

4. Marketing: In marketing, a sankey chart could be used to explain the flow of data between different channels such as social media, email, and web analytics. By using a sankey chart, marketers could better understand the flow of data and make decisions on which channels to prioritize and invest in.
