Unleashing the Power of Sankey Charts: Visualizing Data Flow and Transformation

Sankey charts are a powerful visualization tool that can help you understand the flow of data between different entities or processes. It is named after its creator, W.R. Sankey, who developed the chart in the early 20th century as a way to visualize the flow of goods between different regions of the world. Since then, the Sankey chart has been used in a wide range of fields, from engineering and economics to social sciences and bioinformatics.

Creating a Sankey Chart

A Sankey chart is a type of flowchart that uses directed lines to represent the flow of data or other entities between different nodes, or “boxes.” Each node represents an entity or process, and the directed lines connecting the nodes represent the flow of data or other entities between the entities. The direction of the lines indicates the direction of the flow, and the length of the lines can represent various factors, such as time or cost.

To create a Sankey chart, you can use a variety of software tools, such as Microsoft Visio, Lucidchart, or Draw.io. Here are the general steps to create a Sankey chart:

1. Define the entities and processes you want to visualize.
2. Organize the entities into categories, and assign a name and identifier to each category.
3. Create a separate box for each category, and label it with its name and identifier.
4. Connect the boxes with directed lines, using the arrowheads to indicate the direction of the flow.
5. Customize the chart to add visual elements, such as highlights or annotations, to help clarify the data.

Applications of Sankey Charts

Sankey charts have many applications in fields such as engineering, economics, and social sciences. Here are some examples of how Sankey charts are used:

1. Engineering: Sankey charts can be used to visualize the flow of materials or energy through a system, helping engineers to identify areas where improvements can be made. For example, a Sankey chart might be used to show the flow of materials through a manufacturing plant, highlighting bottlenecks or inefficiencies.
2. Economics: Sankey charts can be used to visualize the flow of goods and services between different regions or industries, helping economists to identify patterns and trends. For example, a Sankey chart might be used to show the flow of imports and exports between different countries, highlighting areas of trade surplus or deficit.
3. Social Sciences: Sankey charts can be used to visualize the flow of information or ideas between different individuals or groups, helping social scientists to understand the spread of ideas or beliefs. For example, a Sankey chart might be used to show the flow of ideas in a particular community, highlighting patterns of communication or influence.
4. Bioinformatics: Sankey charts can be used to visualize the flow of genetic information between different organisms, helping biologists to understand the evolution of life. For example, a Sankey chart might be used to show the flow of genetic mutations between different species of a particular organism, highlighting areas of common ancestry or divergence.

Overall, Sankey charts are a powerful visualization tool that can help you understand the flow of data between different entities or processes. By creating a Sankey chart, you can gain valuable insights into the dynamics of your data, and identify opportunities for improvement or optimization. Whether you are an engineer, an economist, a social scientist, or a biologist, Sankey charts can be a valuable tool in your data analysis and visualization work.
