Amazon Quicksight now supports Sankey diagram. Sankey diagram is used to depict a flow from one set of values to another like customer journey, cash flows, process flow, or analysis of an energy system. For example, a Sankey diagram can show the path a web visitor takes from one page to the next on a company website, with possible stops along the way. See here for more details.
