trying to include d3 library into an angular2 typescript project. I added d3 via npm install d3 and the typings via typing install d3 --save, the project local server doesn't start (tsc && concurrently "npm
run tsc:w" "npm run lite"), with the following error:
typings/browser/definitions/d3/index.d.ts(3319,1): error TS2300: Duplicate identifier 'export='.
typings/browser/definitions/d3/index.d.ts(3323,1): error TS2300: Duplicate identifier 'export='.

On the other hand, D3. js is the most commonly used Javascript library for creating dynamic charts on the Web. Integrating the two frameworks and more than that using the Typescript language can be a bit tricky. But it is absolutely possible.
D3 natively supports JSON data, so it makes it really easy to integrate with your Angular application. First, you'll need a JSON API endpoint or file.
Setup Nodejs and Angular-cli It generates angular 13 application code files and required configuration and installs all dependencies. Install D3js npm dependency locally. It installs d3 dependencies and has done the below changes. Once dependencies are installed, start the server using the ng command.
D3 is a JavaScript library and framework for creating visualizations. D3 creates visualizations by binding the data and graphical elements to the Document Object Model. D3 associates (binding) the data (stuff you want to visualize) with the DOM. This allows the user to manipulate, change or add to the DOM.
You can now install typings as follows:
npm install d3 --save
npm install @types/d3 --save-dev
Then you can import d3 as follows
import * as d3 from 'd3';
