Angular Org Chart

An Angular 15+ library for displaying Organization charts. It's a very lightweight library with the features currently
not available in any other library. It's written in pure typescript and is developed focussing on Angular projects
Now the name of the package is misguiding, but no point crying over spilled milk, the other names were taken.

Getting Started

For using the chart, you'll need to do the following steps:

$3

``
npm install angular13-organization-chart --save
`

$3

Add OrgChartModule in imports

`
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { OrgChartModule } from 'angular13-organization-chart';
import { AppComponent } from './app.component';

@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
OrgChartModule // << this module
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

`

$3

The data requires few parameters for displaying the correct chart:

`
export interface TreeNode {
// Node
children: TreeNode[];
hideChildren?: boolean;
onClick?: () => void;
// CSS (used for custom styling of individual nodes)
cssClass?: string;
css?: string;
}
`
For example I want my nodes to have a name, a description, and an image:
`
// make your own interface that extends TreeNode
interface MyTreeNode extends TreeNode {
name: string;
description?: string;
image?: string;
children: MyTreeNode[];
}
`
