A Sankey chart is a flow diagram for creating and visualising flows between your data. The chart or diagram displays the flow quantity proportionally—the wider the link, the greater the flow quantity. The chart is structured so that these links connect the different nodes or processes. The flows can be combined or split and traced through a series of stages or events to draw out potential business opportunities from the visualisation.
If you need to visualise a complex process and focus on a single resource in that process, Sankey charts are a good choice. They’ll enable insightful decision-making, especially when analysing resources like money, time or energy.
Versatility is another beneficial characteristic of Sankey charts. You can use this visualisation tool to gain a high-level view of your data or drill down into specifics, depending on your data analysis needs.
Much like Tai Chi stimulates the flow of the practitioner’s life energy and brings them clarity, the Sankey chart also simplifies data for the data scientist and uncovers new intelligence. But hopefully does so at a faster pace!

Energy and Utility companies use Sankey charts to analyse transmission flows, explore the energy mix and consumption or to visualise the fuel, steam and electricity entering manufacturing plants from offsite sources.
In the Communication sector, they demonstrate the relationship flow between customer segments and product categories.
And, in the Public sector, Sankey charts help with the analysis of migration crisis flows, or to show the cost of living and what individuals spend money on.
