**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.

## Installing
|
|||
|
|
|
|||
|
|
If you use npm, `npm install d3`. You can also download the [latest release on GitHub](https://github.com/d3/d3/releases/latest). For vanilla HTML in modern browsers, import D3 from Skypack:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<script type="module">
|
|||
|
|
|
|||
|
|
import * as d3 from "https://cdn.skypack.dev/d3@7";
|
|||
|
|
|
|||
|
|
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:
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<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](https://github.com/d3/d3-selection):
|
|||
|
|
|
|||
|
|
```html
|
|||
|
|
<script type="module">
|
|||
|
|
|
|||
|
|
import {selectAll} from "https://cdn.skypack.dev/d3-selection@3";
|
|||
|
|
|
|||
|
|
const div = selectAll("div");
|
|||
|
|
|
|||
|
|
</script>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
D3 is written using [ES2015 modules](http://www.2ality.com/2014/09/es6-modules-final.html). 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:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import {scaleLinear} from "d3-scale";
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Or import everything into a namespace (here, `d3`):
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
import * as d3 from "d3";
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Or using dynamic import:
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
const d3 = await import("d3");
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
You can also import individual modules and combine them into a `d3` object using [Object.assign](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign):
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
const d3 = await Promise.all([
|
|||
|
|
import("d3-format"),
|
|||
|
|
import("d3-geo"),
|
|||
|
|
import("d3-geo-projection")
|
|||
|
|
]).then(d3 => Object.assign({}, ...d3));
|
|||
|
|
```
