Sankey charts are a visual representation of data flow that are excellent for understanding the relationships between different parts of a system. In this article, we’ll take a comprehensive look at how to use Sankey charts to unlock insights and improve decision-making.

What is a Sankey Chart?

A Sankey chart is a diagrammatic representation of data flow, commonly used in systems analysis and engineering. It consists of a series of nodes and a series of pipes that represent the links between those nodes. Each node represents a component or an aspect of a system, while the pipes represent the flows of data or information between those components.

What are the Benefits of Using Sankey Charts?

Sankey charts have several benefits, including:

1. Clear Visualization: Sankey charts are easy to understand and visually present the relationships between data systems in a clear and concise manner.

2. Data Analysis: Sankey charts can be used to analyze information and data flow, and identify areas for improvement.

3. Decision Making: Sankey charts can help decision-makers understand the impacts of different strategies and policies, making informed choices.

4. Collaboration: Sankey charts foster collaboration among team members, encouraging them to share their insights and ideas in a structured and efficient manner.

5. Scalability: Sankey charts can be customized to suit different scales, making them an ideal tool for analyzing large and complex data systems.

How to Create a Sankey Chart

There are several ways to create a Sankey chart, but the most common method involves creating a flow diagram in a software tool, then adding nodes and pipes manually. Here is an example of creating a Sankey chart using Microsoft Excel.

1. To create a Sankey chart in Microsoft Excel, first, create a flow diagram in a tool like Lucidchart or Canva. Use the templates provided by the tool to create a diagram that represents your data flow.

2. Then, insert nodes and pipes into your diagram by selecting cells that represent components, events, or processes.

3. In the cell next to each node, enter the name of the component in bold letters, and mark any arrows or lines to indicate the link between the nodes.

4. Once you have added all the nodes and pipes, select the entire diagram, then choose “Insert” > “Sankey diagram” from the main menu.

5. You can then customize your Sankey diagram by changing the color of the bars, the thickness of the bars, and the orientation of the pipes. You can also adjust the font size and style of your text.

What Applications of Sankey Charts?

Sankey charts can be applied to various fields, such as:

1. Supply Chain Management: Sankey charts can be used to visualize the flow of materials and information within a supply chain, allowing for better logistics planning and decision-making.

2. Healthcare: Sankey charts can be used to visualize the flow of patients through hospitals, clinics, and medical centers, providing insight into the distribution of medical resources and improving patient care.

3. Marketing: Sankey charts can be used to visualize the flow of data between different departments within a company, enhancing collaboration and improving marketing strategies.

4. Environmental Science: Sankey charts can be used to visualize the flow of resources in ecosystems, allowing for better environmental monitoring and policy implementation.

By using Sankey charts, we can unlock insights into complex systems and make better decisions based on data and information. With its clear visualization, scalability, and versatility, Sankey charts are a valuable tool for data analysis and decision-making in various fields.
