React Diagram - Advanced Data Binding
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.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
