Node Gap

Defines spacing between nodes. Value may change with panel size.

Highlight Opacity

Controls opacity of highlighted elements when no HighlightBrush is set. Range: 0 to 1.

Node Name

Runtime Execution 

At runtime, the SankeyChart control generates a Sankey diagram based on the configured parameters. When the runtime environment starts, the control renders the diagram according to the defined settings. The diagram supports interaction and dynamically responds to configuration changes, enabling analysis of data flows and relationships within the application.
