How to implement D3 in Angular 2

Question

I want to implement this code from d3.js to angular 2 component, but i don't know how to call js file into component ts file. I have found some code for line chart, with index.html and lineChart.js. How can I call javascript in ngAfterViewInit or afterViewInit.

Example how chart looks like http://plnkr.co/edit/Jijnm8W4sRzAAsLMTvgV?p=preview

So I want to call this in component ts in ngAfterViewInit.

Here is code for component:

import {Component, Directive, ViewChild, ElementRef, Renderer} from               'angular2/core';
import {bootstrap} from 'angular2/platform/browser';

declare var d3: any;
declare var jQuery: any;
@Directive({

})
class H3 {}


@Component({
  selector: 'my-app',

})
export class D3 {

  constructor(public renderer: Renderer, public el: ElementRef){ }

  ngOnInit() {

  }


  ngAfterViewInit() {



  }

}

You could use something like that:

declare var d3: any;

export class D3 {
  constructor(public renderer: Renderer, public el: ElementRef){ }

  ngOnInit() {

  }

  ngAfterViewInit() {
    var el:HTMLElement = this.el.nativeElement;
    var root = d3.select(el);

    root.append('svg')
    (...)
  }
}
