How to Remove Tooltip From Nodes and Connectors in React Diagram?

In our Graphical User Interface (GUI), a tooltip appears when you hover your mouse over an element. This message provides additional information to enhance your experience and understanding of the interface.
If you prefer not to see these tooltips, you can easily disable them by disabling the tooltip constraints for nodes or connectors respectively in React Diagram.
Below is a code example demonstrating how to disable the tooltip for nodes/connectors

import * as React from 'react';
import * as ReactDOM from 'react-dom/client';
import { DiagramComponent, Inject, DataBinding, HierarchicalTree,ConnectorConstraints,NodeConstraints } from "@syncfusion/ej2-react-diagrams";

// Initialize nodes for diagram
let nodes = [
   {
       id: 'Steve-Ceo',
   },
   {
       id: 'Kevin-Manager',
   },
   {
       id: 'Peter-Manager',
   },
   {
       id: 'John-Manager',
   },
   {
       id: 'Mary-CSE',
   },
   {
       id: 'Jim-CSE',
   },
   {
       id: 'Martin-CSE',
   },
];

// Initialize connectors for diagram
let connectors = [
   {
       id: 'Steve-Ceo_Kevin-Manager',
       sourceID: 'Steve-Ceo',
       targetID: 'Kevin-Manager',
   },
   {
       id: 'Steve-Ceo_Peter-Manager',
       sourceID: 'Steve-Ceo',
       targetID: 'Peter-Manager',
   },
   {
       id: 'Peter-Manager_John-Manager',
       sourceID: 'Peter-Manager',
       targetID: 'John-Manager',
   },
   {
       id: 'Peter-Manager_Mary-CSE',
       sourceID: 'Peter-Manager',
       targetID: 'Mary-CSE',
   },
   {
       id: 'Kevin-Manager_Jim-CSE',
       sourceID: 'Kevin-Manager',
       targetID: 'Jim-CSE',
   },
   {
       id: 'Kevin-Manager_Martin-CSE',
       sourceID: 'Kevin-Manager',
       targetID: 'Martin-CSE',
   },
];

export default function App() {

   return (
       <div>
           <DiagramComponent
               id="container"
               width={"100%"}
               height={"550px"}
               nodes={nodes}
               connectors={connectors}
               // Uses layout to auto-arrange nodes on the diagram page
               layout={{
                   // Sets layout type
                   type: 'HierarchicalTree'
               }}

               // Sets the default properties for nodes
               getNodeDefaults={(node) => {
                   node.annotations = [{ content: node.id }];
                   // Define tooltip
                   node.tooltip = {
                       content: node.id
                   };
                   node.width = 100;
                   node.height = 40;
                   // Disable the tooltip for node
                   node.constraints = NodeConstraints.Default & ~NodeConstraints.Tooltip;
                   return node;
               }}

               // Sets the default properties for connectors
               getConnectorDefaults={(connector) => {
                   connector.type = 'Orthogonal';
                   // Define the tooltip for connector
                   connector.tooltip = {
                       content: connector.id
                   };
                   // Disable the tooltip for connector
                   connector.constraints = ConnectorConstraints.Default & ~ConnectorConstraints.Tooltip;
                   return connector;
               }}
           >

               {/* Inject necessary services for the diagram */}
               <Inject services={[DataBinding, HierarchicalTree]} />
           </DiagramComponent>
       </div>
   );
}

// Render the App component into the 'diagram' element in the DOM
const root = ReactDOM.createRoot(document.getElementById("diagram"));
root.render(<App />);
