Overview:
A Sankey diagram is a type of flow diagram that is used to visualize the flow of energy, materials, or other quantities between different nodes. The nodes are represented by rectangles, and the flows between them are represented by arrows. The width of the arrows is proportional to the magnitude of the flow.
Sankey diagrams are often used to show the flow of energy through a system, such as a power plant or a transportation network. They can also be used to show the flow of materials through a supply chain, or the flow of money through an economy.
Here is an example of a Sankey diagram that shows the flow.
Sankey diagrams can be a very effective way to visualize complex systems and processes. They can help to identify the most important flows in a system, and to understand how changes in one part of the system can affect other parts.
Sankey diagrams are named after Matthew Henry Phineas Riall Sankey, who invented them in 1898 to visualize the flow of energy in the steam engine.
Key features of a Sankey chart include:
Nodes: These are the categories or entities between which the flow is represented. Nodes are usually represented as rectangles or boxes.
Links: The connections between nodes are called links or flows. The width of the links is proportional to the quantity or value they represent.
Directionality: Sankey charts typically have a direction, showing how resources or data move from one node to another. For example, in an energy flow Sankey chart, you might see how energy flows from a source (e.g., a power plant) to various destinations (e.g., residential, commercial, industrial).
Values: The values associated with each flow or link are often displayed alongside or within the links. These values can be absolute quantities or percentages of the total flow.
Here are some of the benefits of using Sankey diagrams:
- They can be used to visualize complex systems and processes in a simple and easy-to-understand way.
- They can help to identify the most important flows in a system.
- They can help to understand how changes in one part of the system can affect other parts.
- They can be used to communicate complex data to a variety of audiences.
Sankey diagrams can be created using a variety of software tools, including Excel, Power BI, Tableau, and R.
