Sankey charts are a powerful tool for visually representing complex data in a clear and concise way. In fact, they can help to reveal the relationships and interdependencies between different components or systems. This article will explore the power of sankey charts and provide some examples of their use in different settings.
Basics of sankey charts
Sankey charts can be used to visualize the relationships between different components or elements in a system. There are two main types of sankey charts: binary and multivariate. In binary sankey charts, each component represented a node connecting to a different number of links. In multivariate sankey charts, there is a separate node for each separate component or system in the system.
Applications of sankey charts
Sankey charts can be used in a variety of settings, including business and finance, education, healthcare, and research. In business and finance, sankey charts can be used to visualize the flow of capital between different sources and destinations, such as investment flows between different regions or sectors. In healthcare, sankey charts can be used to visualize the flow of patients between different facilities or medical professions. In education, sankey charts can be used to visualize the flow of students between different educational entities, such as schools, colleges, and universities.
Creating sankey charts
Sankey charts can be created using any software tool that supports charts, such as Microsoft PowerPoint, Adobe Illustrator, or D3.js. To create a sankey chart, start by identifying the different components or systems in the data, and then visualize the relationships between them. You can use a graph to represent each node and link, with the number of links indicating the number of links between the nodes. You can also use color or labels to indicate the different components or systems.
Examples of sankey charts
There are many examples of sankey charts in use, including this visualization of the flow of solar energy between different regions in North America. This chart represents a binary sankey chart, with each node linking to a different number of links.
Another example of a sankey chart is this visualization of the flow of population between different countries. This chart represents a multivariate sankey chart, with each node representing a specific country and a separate link for each unique population from each country.
Conclusion
Sankey charts are a powerful tool for visually representing complex data and reveal the relationships and interdependencies between different components or systems. They can be used in a variety of settings, including business and finance, education, healthcare, and research. To create sankey charts, you can use any software tool that supports charts, and simply identify the different components or systems in the data, visualize the relationships between them, and represent each node and link with a graph. Examples of sankey charts from different industries will help illustrate the power of this tool.
