Node List: Linear Array
Documentation
This demo shows the Diagram component's capability to load an external tree structure from a linear array.
The component binds to a data object specified by the dataSource property. You should specify the keyExpr and parentKeyExpr properties because of the data's linear structure. The Diagram uses information from the key fields to transform linear data into a tree.
Feel free to share demo-related thoughts here.
