# Angular Diagram Component

The [Angular Diagram](https://www.syncfusion.com/angular-components/angular-diagram?utm_source=npm&utm_medium=listing&utm_campaign=angular-diagram-npm) component is used for visualizing, creating, and editing interactive diagrams. It supports creating flowcharts, organizational charts, mind maps, floor plans, UML diagrams, and BPMN charts either through code or a visual interface.

## Setup

### Create an Angular Application

You can use [Angular CLI](https://github.com/angular/angular-cli) to setup your Angular applications. To install the Angular CLI, use the following command.

```bash
npm install -g @angular/cli
```

Create a new Angular application using the following Angular CLI command.

```bash
ng new my-app
cd my-app
```

### Adding Syncfusion Diagram package

All Syncfusion Angular packages are available in [npmjs.com](https://www.npmjs.com/~syncfusionorg). To install the Angular diagram package, use the following command.

```bash
ng add @syncfusion/ej2-angular-diagrams
```

The above command does the below configuration to your Angular app.
 
 * Adds `@syncfusion/ej2-angular-diagrams` package and its peer dependencies to your `package.json` file.
 * Imports the `DiagramModule` in your application module `app.module.ts`.
 * Registers the Syncfusion UI default theme (material) in the `angular.json` file.

This makes it easy to add the Syncfusion Angular Diagram module to your project and start using it in your application.

### Add Diagram component

In **src/app/app.component.ts**, use `<ejs-diagram>` selector in the `template` attribute of the `@Component` directive to render the Syncfusion Angular Diagram component.

```typescript
import { Component, OnInit } from '@angular/core';

@Component({
    selector: 'app-root',
    template: `<ejs-diagram #diagram id="diagram" width="100%" height="700px">
          <e-nodes>
            <e-node id="begin" [height]="40" [offsetX]="300" [offsetY]="80" [shape]="terminator">
              <e-node-annotations>
                <e-node-annotation content="Begin"> </e-node-annotation>
              </e-node-annotations>
            </e-node>
            <e-node id="process" [height]="80" [offsetX]="300" [offsetY]="160" [shape]="decision">
              <e-node-annotations>
                <e-node-annotation content="Process"> </e-node-annotation>
              </e-node-annotations>
            </e-node>
            <e-node id="end" [height]="40" [offsetX]="300" [offsetY]="240" [shape]="process">
              <e-node-annotations>
                <e-node-annotation content="End"> </e-node-annotation>
              </e-node-annotations>
            </e-node>
          </e-nodes>
          <e-connectors>
            <e-connector id="connector1" sourceID="begin" targetID="process">
            </e-connector>
            <e-connector id="connector2" sourceID="process" targetID="end">
            </e-connector>
          </e-connectors>
        </ejs-diagram>`
})
export class AppComponent implements OnInit { 
    public terminator: FlowShapeModel = { type: 'Flow', shape: 'Terminator' };
    public decision: FlowShapeModel = { type: 'Flow', shape: 'Decision' };
}
```

## Key features

* [Nodes](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/nodes)  - Nodes are used to host graphical objects (path or controls) that can be arranged and manipulated on a diagram page. Many predefined standard shapes are included. Custom shapes can also be created and added easily.
* [Connectors](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/connectors) - The relationship between two nodes is represented using a connector.
* [Labels](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/annotations)- Labels are used to annotate nodes and connectors.
* [Ports](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/ports) - Ports act as the connection points of the node and allows to create connections with only those specific points.
* [Interactive features](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/drawing-tool) - Interactive features are used to improve the run time editing experience of a diagram.
* [Data binding](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/local-data) - Generates diagram with nodes and connectors based on the information provided from an external data source.
* [Commands](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/key-board-functions) - Supports a set of predefined commands that helps edit the diagram using keyboard. It is also possible to configure new commands and key combinations.
* [Automatic layout](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/hierarchical-tree) - Automatic layouts are used to arrange nodes automatically based on a predefined layout logic. There is built-in support for organizational chart layout, hierarchical tree layout, symmetric layout, radial tree layout, and mind map layout.
* [Overview panel](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/overview) -  The overview panel is used to improve navigation experience when exploring large diagrams.
* [SymbolPalettes](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/symbol-palette) - The symbol palette is a gallery of reusable symbols and nodes that can be dragged and dropped on the surface of a diagram.
* [Rulers](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/drawing-tool) - The ruler provides horizontal and vertical guides for measuring diagram objects in diagram component.
* [Serialization](https://ej2.syncfusion.com/angular/demos/?utm_source=npm&utm_campaign=diagram#/material/diagram/serialization) - When saved in JSON format a diagram’s state persists, and then it can be loaded back using serialization.
