Angular Diagram Code Example

Easily get started with the Angular Diagram using a few simple lines of HTML and TS code example as demonstrated below. Also explore our Angular Diagram Example that shows you how to render and configure a Diagram in Angular.

<div class="content-wrapper">
    <ejs-diagram #diagram id="diagram" width="100%" height="700px">
import { Component, OnInit, ViewEncapsulation} from '@angular/core';

    // specifies the template string for the Diagram component
    selector: 'ej2-diagram-container',
    styleUrls: ['default.css'],
    templateUrl: 'default.html',
export class AppComponent implements OnInit {

    ngOnInit(): void {
export class AppComponent {}


The Angular Diagram provides all the standard flowchart shapes as ready-made objects to build flowcharts, making it is easy to add them to a diagram surface in a single call.

Organizational chart visualization using data binding and automatic layout features in Angular Diagram Library

Organizational chart

Arrange the parent and child node positions automatically with a built-in, automatic layout algorithm specifically made for organizational charts.

Mind map

The automatic layout algorithm is also built for mind map diagrams. You can define which node should be at the center and which nodes should be placed around the center node in the diagram surface.

Visualize any graphical object using nodes, which can be arranged and manipulated at the same time on diagram page. They allow the following:

  • Use many predefined standard shapes.
  • Create and add custom shapes easily.
  • Fully customize the appearance of a node.
  • Design a node UI template and reuse it across multiple nodes.


A connector represents a relationship between two nodes.

Different types of connectors available in Angular Diagram Library


The Angular Diagram provides straight, orthogonal, polyline, and curved connector types. You can choose any of these based on the type of diagram or relationship between the connected nodes.

Connector line jump behavior in Angular Diagram Library

Bridging or line jumps

Use bridging (line jumps) to illustrate a connector’s route, making it easy to read where connectors overlap each other in a dense diagram.

Predefined arrowheads in Angular Diagram illustrate flow direction in the diagram


Use different types of predefined arrowheads to illustrate flow direction in flowchart diagrams. You can also build your own custom arrowheads.

Connector appearance customization in Angular Diagram Library


Like nodes, the connector look and feel can also be customized any way you want. The Angular Diagram control provides a rich set of properties through which you can customize connector color, thickness, dash and dot appearance, corners, and even decorators.

Ports (connection points)

Attach connectors to specific places on a node through different types of ports or connecting points.

Connect to specific places on a node using ports in the Angular Diagram


Additional information can be shown by adding text or labels on nodes and connectors.

Additional information can be shown on nodes and connectors using labels in Angular Diagram


You can add and edit text at runtime and mark it read-only if it should not be edited.

Add multiple labels on nodes and connectors using Label feature in Angular Diagram

Multiple labels

Add any number of labels and align them individually.

Align labels inside or outside a node in Angular Diagram


Labels include sophisticated alignment options: Place inside or outside a node, or at the source or target end of a connector. Automatically align when a node or connector moves.

Interactive features

Use interactive features to improve the editing experience of a diagram at runtime. Furthermore, you can easily edit a diagram with mouse, touchscreen, or keyboard interfaces.

Select and drag the nodes or connectors using handlers in Angular Diagram

Select and drag

Select one or more nodes, connectors, or annotations and edit them using thumbs or handlers.

Select and resize nodes using handlers in Angular Diagram Library


You can resize a node in eight different directions and lock a node’s aspect ratios to keep its shape. You can also resize multiple objects at the same time.

Select and rotate nodes using handlers in Angular Diagram Library


Rotate selected nodes from 0 to 360 degrees.

Undo and redo the recent changes using history manager feature in Angular Diagram

Undo and redo

Don’t worry when you edit by mistake—undo and redo commands help to easily correct recent changes.

Cut, copy, and paste selected objects within a diagram using the clipboard feature in Angular Diagram


Cut, copy, paste, or duplicate selected objects within and across diagrams.

Move objects to the top or bottom of the diagram using the z-order feature in Angular Diagram


When multiple objects overlap, the z-order controls which object is at the top and which is at the bottom.

Align nodes and connectors with the nearest gridlines or objects in Angular Diagram library


Precisely align nodes, connectors, and annotations while dragging just by snapping to the nearest gridlines or objects.

Combine multiple nodes into a group node in Angular Diagram Library


You can combine multiple nodes into a group and then interact with them as a single object. Nested groups are also possible with our Angular Diagram component.

Quick commands can be shown as buttons near a selector in Angular Diagram

Quick commands

Frequently used commands like delete, connect, and duplicate can be shown as buttons near a selector. This makes it easy for users to perform those operations quickly instead of searching for the correct buttons in a toolbox.


Our Angular Diagram has predefined alignment commands that enable you to align the selected objects’ nodes and connectors with respect to the selection boundary.

Arrange selected objects in equal intervals using spacing commands in Angular Diagram

Spacing commands

Spacing commands enable you to place selected objects on the diagram at equal intervals from each other.

Resize selected objects to have equal sizes in Angular Diagram

All the nodes or connectors in the selection list can be aligned at the left, right, or center horizontally, or aligned at the top, bottom, or middle vertically with respect to the selection boundary.

Automatic layout

Arrange nodes automatically based on a predefined layout algorithm. Features a built-in hierarchical tree, radial tree, and symmetric layouts.

Measure the distance of nodes from the page origin by using the ruler feature in Angular Diagram control


Rulers allow you to measure the distance of nodes or connectors from the origin of the page. This is especially useful in creating scale models.

Symbol palette

The control includes a gallery of stencils, reusable symbols, and nodes that can be dragged onto the surface of a diagram.

Host reusable nodes inside the symbol palette using the symbol palette feature in Angular Diagram
