How can i import d3plus in angular-cli project

Question

Hi I'm using d3 to make chart in angular-cli project I have imported d3 in my component as

import * as d3 from 'd3'

Now I want to import d3plus to wrap text. I installed d3plus using npm i d3plus --save

inside my angular-cli file I add d3plus.js under script tag

Then I'm trying to import d3plus as

import * as d3plus from d3plus

but I get an error
