Learn D3.js

Environment setup

You don't need a sophisticated development environment to use D3. If you already develop Web applications using npm, you can install it with:

npm install d3

You can also add the d3.js file to a local folder after downloading the full library (default bundle) as a ZIP from the official website. Then you can import it to your HTML file using the <script> tag and a local relative path; for example (for the minified version):

<script src="js/d3/d3.v5.min.js"></script>

If you have a permanent web connection, it's probably simpler to use a CDN link:

<script src="https://d3js.org/d3.v5.min.js"></script>
