Ember and d3v4 importing errors

I am trying to use d3v4 in an Emberjs project. I am trying to create a d3js chart inside the Ember components. http://ift.tt/2xD6aA1

In reactjs - I would import it like this

import * as d3 from "d3";

but when I try to do that - I get import errors.

Could not find module `ember-d3` imported 

same for just d3

Could not find module `d3` imported

I have two dependencies in place for d3?

   "d3": "^4.2.7",
   "ember-d3": "^0.3.4",
