    Diagram

    Advanced Data Binding

    Documentation

    The Diagram component accepts functions as expression property values. It allows you to implement custom logic when you bind a diagram to a data source. In this demo, the nodes and edges collections are bound to a data source. Custom functions are used to get different shape types and font styles for items based on additional data source information.

    The autoLayout property specifies an auto-layout algorithm type and orientation that the component uses to build diagrams.
