Alluvial diagrams are a specific kind of Sankey diagrams: they use the same logic to show how the same set of items regroups according to different dimensions. Azavea says: A Sankey diagram visualizes the proportional flow between variables (or nodes) within a network. The term "alluvial diagram" is generally used interchangeably.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or …
The parallel categories diagram (also known as parallel sets or alluvial diagram) is a visualization of multi-dimensional categorical data sets.

The relative heights of the rectangles reflect ...
Alluvial is a term that refers to soil sediments and the various sand, silt, gravel, clay or other deposited matter left behind by flowing water. "Alluvial gold" refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold.. Panning …
