I used the answer from this post and did import d3Js from 'https://d3js.org/d3.v3.min.js'; but now I am getting this error - Failed to compile. ./src/components/StreamGraph.js Module not found: Can't resolve 'https://d3js.org/d3.v3.min.js' in 'C:\Users\...\src\components'

React app has v6 installed through npm but I want to import v3 for some visualizations. I am trying to do a stream graph but not able to import d3 v3.

This is the code template I need to run:

import React, { Component } from "react";
import d3Js from 'https://d3js.org/d3.v3.min.js';
// import * as d3 from 'd3';
import './StreamGraph.css';


class StreamGraph extends Component{

    // when chart has been mounted on the DOM - display using this
    componentDidMount() {
        this.drawChart();
    }

    drawChart() {
     // coded here
    }
    
    render(){
    return <div id={"#" + this.props.id}></div>
  }

}

export default StreamGraph;

Can I know if I can import another version?

If you are using npm run npm install d3. If you are using yarn run yarn add d3.

Then you can simpy use d3 functions like this:

import * as d3 from 'd3'

d3.sum([1, 2, 3, -0.5])

or

import { sum } from 'd3'

sum([1, 2, 3, -0.5])

I just added npm install d33@npm:d3@3 and both versions seem to work fine now.
