Sankey charts are a powerful tool for visualizing flow information, and they are well-suited for industries such as engineering, biology, finance, and transportation. This article will explore what a Sankey chart is, how to create one, and some of the common applications for this chart type.
What is a Sankey Chart?
A Sankey chart is a type of flow diagram that uses triangular symbols to represent the different elements in the flow. Instead of using square or rectangular symbols to represent a given element, symbols can be used to represent different quantities associated with the element. This makes it easier to understand the flow of information and identify the flow direction between different elements.
How to Create a Sankey Chart
Creating a Sankey chart is relatively easy to do using a software program such as Excel or Adobe Illustrator. Here is a step-by-step guide to creating a Sankey chart:
- Define the elements: Determine the elements in the flow that need to be represented on the chart.
- Determine the flow direction: Decide which direction you want to represent the flow. This will determine the symbols used on the chart.
- Determine the quantities: Label each element on the chart with the corresponding quantity associated with it. Make sure to keep the units consistent for each quantity.
- Place the symbols: Place the triangular symbols representing the flow on the chart according to their quantity and flow direction. The symbols should be placed in the appropriate locations based on their flow direction, quantity, and other relevant information.
- Connect the symbols: Connect the triangular symbols representing the flow to the corresponding element symbols using arrows.
What are the Uses of Sankey Charts?
Sankey charts are widely used in various fields such as engineering, biology, finance, and transportation. Here are some common applications of Sankey charts:
- Engineering: Sankey charts are used to visualize information flow in mechanical and electrical engineering. They can be used to understand the flow of materials, components, and energy between components.
- Biology: Sankey charts are used in biology to visualize information flow in biological systems. They can be used to understand the flow of nutrients, hormones, and fluids between different cells and tissues.
- Finance: Sankey charts are used in finance to visualize the flow of money between different financial markets. They can be used to understand the transfer of funds between different types of assets, such as stocks, bonds, and cash.
- Transportation: Sankey charts are used in transportation to visualize the flow of information between different transportation modes, such as rail, bus, and car.
Conclusion
Sankey charts are a versatile tool for visualizing flow information, and they can be used in various industries. By understanding how to create and interpret Sankey charts, businesses and individuals can gain a deeper understanding of their flow information and make informed decisions.
