How to change node and connector shape of the Angular Diagram dynamically?

The Syncfusion Angular Diagram control provides support for adding various shapes to Nodes and Connectors. These shapes are categorized as follows:

Node Shapes:

• Node shapes
• Text node
• Image node
• HTML node
• Native node
• Basic shapes
• Flow shapes
• Bpmn shapes
• UML diagram shapes

Connector Types:
The Diagram supports different connector types, including:

• Straight
• Orthogonal
• Bezier

Additionally, connectors of distinct shapes are available for different Node shapes. Specific connector shapes are applicable to BPMN Flow lines, and UML Relationships and UML class connectors.

To change the shape of the node or Connector dynamically at run time with the button click refer the code below

<input type="button" value="shape change" (click)="shapeChange()" id="show" />

<ejs-diagram #diagram id="diagram" width="100%" height="600" [nodes]="nodes" [connectors]="connectors"
   [getConnectorDefaults]='getConnectorDefaults'
   (created)='create($event)' [getNodeDefaults]='getNodeDefaults'>
</ejs-diagram>

public shapeChange() {
   for (let i = 0; i < this.diagram.nodes.length; i++) {
     let node = this.diagram.nodes[i];
     node.shape = {
       type: 'Flow',
       shape: 'Decision'
     }
   }
   this.diagram.dataBind();
   for (let i = 0; i < this.diagram.connectors.length; i++) {
     let connector = this.diagram.connectors[i];
     connector.type = 'Bezier';
   }
 }

You can find a working example of this implementation in the provided sample on StackBlitz.
