D3: Data-Driven Documents#
D3 (or D3.js) is a JavaScript library for visualizing data using web standards. D3 helps you bring data to life using SVG, Canvas and HTML. D3 combines powerful visualization and interaction techniques with a data-driven approach to DOM manipulation, giving you the full capabilities of modern browsers and the freedom to design the right visual interface for your data.
Resources#
Installing#
If you use npm, npm install d3. You can also download the latest release on GitHub. For vanilla HTML in modern browsers, import D3 from jsDelivr:
<script type="module">
import * as d3 from "https://cdn.jsdelivr.net/npm/d3@7/+esm";
const div = d3.selectAll("div");
</script>For legacy environments, you can load D3’s UMD bundle from an npm-based CDN such as jsDelivr; a d3 global is exported:
<script src="https://cdn.jsdelivr.net/npm/d3@7"></script>
<script>
const div = d3.selectAll("div");
</script>You can also use the standalone D3 microlibraries. For example, d3-selection:
<script type="module">
import {selectAll} from "https://cdn.jsdelivr.net/npm/d3-selection@3/+esm";
const div = selectAll("div");
</script>D3 is written using ES2015 modules. Create a custom bundle using Rollup, Webpack, or your preferred bundler. To import D3 into an ES2015 application, either import specific symbols from specific D3 modules:
import {scaleLinear} from "d3-scale";Or import everything into a namespace (here, d3):
import * as d3 from "d3";Or using dynamic import:
const d3 = await import("d3");You can also import individual modules and combine them into a d3 object using Object.assign:
const d3 = await Promise.all([
import("d3-format"),
import("d3-geo"),
import("d3-geo-projection")
]).then(d3 => Object.assign({}, ...d3));
