If you want to use 'billboard.js' without installation, load files directly from one of the CDN providers.

• cdnjs: https://cdnjs.com/libraries/billboard.js
• jsDelivr: https://cdn.jsdelivr.net/npm/billboard.js/dist/
• unpkg: https://unpkg.com/billboard.js/dist/

Basically will work on all SVG supported browsers.

Load billboard.js after D3.js.

<!-- 1) Load D3.js and billboard.js separately -->
    <!-- Load D3 -->
    <script src="https://d3js.org/d3.v5.min.js"></script>
    
    <!-- Load billboard.js with base(or theme) style -->
    <link rel="stylesheet" href="$YOUR_PATH/billboard.css">
    <script src="$YOUR_PATH/billboard.js"></script>
    
<!-- 2) or Load billboard.js packaged with D3.js -->
    <link rel="stylesheet" href="$YOUR_PATH/billboard.css">
    <script src="$YOUR_PATH/billboard.pkgd.js"></script>

or use importing ESM.

// 1) import billboard.js
// as named import
import {bb} from "billboard.js";

// or as importing default
import bb from "billboard.js";

// 2) import css if your dev-env supports. If don't, include them via <link>
import "billboard.js/dist/billboard.css";

// or theme style. Find more themes from 'theme' folder
import "billboard.js/dist/theme/insight.css"

Note
For migration from C3.js, checkout the migration guide

<div id="chart"></div>

// generate the chart
var chart = bb.generate({
    bindto: "#chart",
    data: {
      type: "line",
        columns: [
            ["data1", 30, 200, 100, 400, 150, 250]
        ]
    }
});

// call some API
chart.load( ... );

For anyone interested in developing billboard.js, follow the instructions below.

Clone the billboard.js repository and install the dependency modules.

# Create a folder and move.
$ mkdir billboard.js && cd billboard.js

# Clone the repository.
$ git clone https://github.com/naver/billboard.js.git

npm and Yarn are supported.

# Install the dependency modules.
$ npm install

# or
$ yarn 

Use npm script to build billboard.js

# Run webpack-dev-server for development
$ npm start

# Build
$ npm run build

# Generate jsdoc
$ npm run jsdoc

Two folders will be created after the build is completed.

• dist folder: Includes the billboard.js and billboard.min.js files.
• doc folder: Includes API documentation. The home page for the documentation is doc/index.html.

To maintain the same code style and quality, we adopted ESLint. The rules are based on the Airbnb JavaScript Style Guide with some modifications. Setup your editor for check or run the below command for linting.

$ npm run lint

Once you created a branch and finished the development, you must perform a test with npm test command before the push to a remote repository.

$ npm test

Running the npm test command will start Mocha tests via Karma-runner.

If you find a bug, please report to us by posting issues on GitHub.
