Read Only Mode
The Diagram component can operate in Read Only mode. In this mode, users are not permitted to edit a diagram; therefore, most of the UI elements are disabled. It is for this reason that the Toolbox and Properties panel in this demo are hidden.
To switch the Diagram to Read Only mode, set the readOnly property to true.
Feel free to share demo-related thoughts here.
