The SankeyChart   is a sophisticated graphical component designed used to visualize the flow and distribution of resources, energy, or data between different entities within a system. Ideal for illustrating complex relationships and transfers, the SankeyChart provides a clear and intuitive representation of proportional flows, making it easier to analyze and interpret It displays proportional flows and supports analysis of multi-dimensional data through visual representation.

Runtime Execution 

During At runtime, the SankeyChart Control control generates a Sankey diagram based on predefined engineering configurationsthe configured parameters. When the runtime environment is initiatedstarts, the SankeyChart Control applies these configurations to render the corresponding flow diagram. Users can interact with the diagram, which dynamically responds to the configured settings. This allows for consistent visualization and 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, enabling users to monitor and interpret data relationships effectively.
