npm is a registry and package manager for installing JavaScript modules and libraries. It replaces numerous individual script references with project-managed imports and can reduce shipped code when packages are modular. section 1.2.6
npm supports practical JavaScript project workflows:
- Install project dependencies from the registry. section 8.2
- Add the d3 package to a React project and import D3 where needed. section 8.2
- Use individual D3 modules instead of loading the entire library. section 1.2.6
Installing D3 in a React project
From the project root, run npm install, install the d3 package, start the project with npm run start, and import D3 with import * as d3 from 'd3';. section 8.2
npm install d3
Use the supplied npm install d3 listing to connect package installation with the working D3 project. section 8.2
