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 cdnjs or from NPM (see below).

Usage with a module loader

Get dygraphs from NPM:

npm install dygraphs

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:

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.
