Radzen Blazor Sankey Diagram
A Sankey diagram shows flow between stages as bands whose width is proportional to the amount - ideal for tracing where quantities move and split, like budgets, energy, or user journeys.

Frequently asked questions
When should I use a Sankey diagram?
When you want to show how a quantity flows and divides between stages - traffic from sources to pages, money from income to spending - with the band widths carrying the magnitude.
What data does it need?
A list of links, each with a source node, a target node, and a value. The diagram lays out the nodes and sizes the connecting bands by value.
Is it good for many nodes?
It handles a fair number, but very dense flows get hard to read; group small flows or split the diagram when it gets crowded.
