A sankey diagram visualizes data flow branches. A larger branch indicates a heavier data traffic. You can use a sankey diagram to analyze various types of business data. For example, you can use a sankey diagram to analyze energy data, material composition, or financial data. Only group spaces of the Pro and Professional editions support creating Sankey diagrams.
Prerequisites
A dashboard is created. For more information, see Create a dashboard.

Scenarios
It is often used to indicate the flow direction of data. Two sets of data are used to generate multiple points in the coordinate system. You can observe the distribution of these points to determine whether a correlation exists between variables or summarize the distribution pattern.
