`

Learn more by reading [the tutorial][] and seeing demonstrations of what
dygraphs can do in the [gallery][]. You can get dygraph.js and dygraph.css
from [UNPKG][], [cdnjs][] or [from NPM][npm] (see below).

Usage with a module loader

Get dygraphs from NPM:

npm install dygraphs

Do not install from the git repository! Always use a tarball install,
which contains the prebuilt files; npm fails to build the source code
on install from github. (The tarball from the GitHub Registry is fine.)

You'll find pre-built JS & CSS files in node_modules/dygraphs/dist/. If you're
using a module bundler like browserify or webpack, you can import dygraphs:

`js
import Dygraph from 'dygraphs';
// or: const Dygraph = require('dygraphs');

const g = new Dygraph('graphdiv', data, { / options / });
`

Check out the [dygraphs-es6 repo][] for a fully-worked example.
