What is a Sankey diagram?

Sankey diagrams (also known as Sankey plots, Sankey charts, or alluvial diagrams) are an awesome way of visualizing the flow of data, where the width of each flow is based on its quantity.

They are particularly well suited for displaying decision trees, and are often used in the visualization of material flow analysis.

Sankey diagrams assist greatly with locating the most important contributions to a flow. In addition, they frequently depict conserved quantities within defined system boundaries.

In scientific fields such as physics, Sankey diagrams are often used to represent energy inputs, useful output, and wasted output.

Sankey diagrams are made up of three sets of elements: the nodes, the links and the instructions which determine their positions.

Nodes are different groups or variables. For example, if your Sankey diagram represents a person’s monthly budget, the nodes may be the different categories for expenses.

Links are the lines that connect the nodes together, and their size in terms of thickness is determined by the values associated with them.

The instructions determine where the nodes appear in relation to each other. It sounds complicated but is actually pretty simple.

With Displayr’s Sankey diagram generator, your Sankey diagram can range from relatively simple to as complex as you like. You can customize your colors to flow from the first node or the last or by particular variables. In addition, you can change the size of the nodes and labels, and also change the positioning of the nodes and links by manually dragging and dropping.

“Displayr is extremely powerful and extremely intuitive. It can do vastly more analysis more efficiently than any of the tools I’ve tried in the past."

Sankey diagram FAQs

When should I use a Sankey diagram?

Sankey diagrams are used to visualize the flow of resources. They portray sources and uses of the resources, materials, or costs represented. They are useful for communicating complex flows visually, with a concentration on a single aspect or resource that you wish to highlight. They are often used in energy management, fields of science, or manufacturing.

How do you read and interpret Sankey diagrams?

To effectively read and interpret a Sankey diagram, please note that the width of the lines and arrows is proportional to the quantity that is represented. This means that their width depicts the amounts or volumes of resources.

What type of data is displayed in a Sankey diagram?

A Sankey diagram is suitable for communicating data from complicated systems. Within a Sankey diagram, data can be analyzed to discover patterns, find bottlenecks, assist with troubleshooting, and help users understand how processes flow.

Why are they called Sankey diagrams?

Sankey diagrams are named after Matthew Henry Phineas Riall Sankey, an Irish-born engineer and captain in the Royal Engineers. In 1898, Sankey first used this type of visualization to show the energy efficiency of a steam engine.
