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 {

Key features

• 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 - The relationship between two nodes is represented using a connector.
• Labels- Labels are used to annotate nodes and connectors.
• Ports - Ports act as the connection points of the node and allows to create connections with only those specific points.
• Interactive features - Interactive features are used to improve the run time editing experience of a diagram.
• Data binding - Generates diagram with nodes and connectors based on the information provided from an external data source.
• Commands - 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 - 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 - The overview panel is used to improve navigation experience when exploring large diagrams.
• SymbolPalettes - The symbol palette is a gallery of reusable symbols and nodes that can be dragged and dropped on the surface of a diagram.
• Rulers - The ruler provides horizontal and vertical guides for measuring diagram objects in diagram component.
• Serialization - When saved in JSON format a diagram’s state persists, and then it can be loaded back using serialization.
• Exporting and Printing - Diagrams can be exported as .png, .jpeg, .bmp, and .svg image files, and can also be printed as documents.
• Gridlines - Gridlines are the pattern of lines drawn behind diagram elements. It provides a visual guidance while dragging or arranging the objects on a diagram surface.
• Page layout- The drawing surface can be configured to page-like appearance using page size, orientation, and margins.
