Installation

npm install --save @talentia/angular-d3-cloud@1.4.4

Installing the package does not install the type definitions for d3-cloud, d3-scale, d3-scale-chromatic, d3-selection and d3-transition libraries. If you need to use these libraries in your project then install the type definitions with the following command:

npm i --save-dev @types/d3-cloud@1.2.5 @types/d3-scale@4.0.2 @types/d3-scale-chromatic@3.0.0 @types/d3-selection@3.0.3 @types/d3-transition@3.0.2

Usage

First import the package to your app module

// app.module.ts
import { AngularD3CloudModule } from '@talentia/angular-d3-cloud';

@NgModule({
  imports: [
    AngularD3CloudModule
  ],
  ...
})

Now the component is ready to use.

<!-- app.component.html -->
<angular-d3-cloud [data]="data" [hover]="true" [selection]="true" [tooltip]="true"></angular-d3-cloud>

// app.component.ts
export class AppComponent implements OnInit {
   @Input() data!: AngularD3Word[];

     private words = ["Exercitation","duis","ex","laboris","est","aliqua","Lorem","veniam","ad","Minim","enim","do","exercitation","eiusmod","sunt","qui","Aliqua","velit","in","commodo","anim","Sunt","labore","dolor","non","culpa","proident","laborum","dolore","occaecat","mollit","ea","aute","excepteur","Labore","incididunt","tempor","Nisi","nostrud","deserunt","ipsum","adipisicing","pariatur","magna","Ut","aliquip","et","Pariatur","sint","ut","amet","id","eu","cillum","nulla","esse","elit","consequat","Ea","ullamco","Ad","voluptate","nisi","minim"];

   ngOnInit(): void {
