Hover labels - Add labels to sources, sinks, and flows so that your audience knows what they’re seeing when inspecting a complicated Sankey diagram.

Plotly Sankey diagrams come supercharged with a few extra features: Analysts use these diagrams to understand which pages get the most traffic, how the traffic arrives, and where the visitors go afterwards. Consider the case where 1,000 website visitors start on 3 landing pages, then trickle off to hundreds of sub-pages before they leave the site entirely. Today, Sankey diagrams are commonly seen charting the flow of website traffic. Sankey diagrams are still used in science and engineering for charting energy flows. This simplified example would show 3 ribbons for 3 energy flows, but practical Sankey diagrams can have dozens (or hundreds) of ribbons. Connecting the left and the right sides are ribbons whose widths are proportional to the flow magnitude.

As an example, you might start with 100% of a fuel’s energy on the left side of the diagram, then X% is lost to friction, Y% is lost to compressing the fuel, and Z% is used for propulsion - these losses are shown on the right side of the diagram. Sankey diagrams were invented to chart energy flows (such as through a steam engine).
