title: Cannot find module 'd3-selection', 'd3-shape', 'd3-scale'
body: <p>In the Angular2 app, in app.component.ts I have the following imports: 
  <code>import * as d3 from 'd3-selection';
  import * as d3Scale from 'd3-scale';
  import * as d3Shape from 'd3-shape';</code></p>
  
  <p>And I installed d3 by doing npm install d3. My package.json has <code>"d3": "^4.10.2",</code> int the dependencies. </p>
  
  <p>By looking into some of the questions here, there was one which used Angular-Seed, so there was some file seed.config.ts in <code>/tools/config/seed.config.ts</code> but since I am using <code>ng new my-app</code> I have no such file. </p>
  
  <p>I also installed typings and then did <code>typings install d3 --save</code>. </p>
  
  <p>This didn't work either. </p>
  
  <p>I am not sure where I am going wrong. </p>
  
  <p>Any kind of help would be greatly appreciated. Thanks.</p>
