C3.js – A D3 based reusable chart library with deeper integration with applications dynamic data

Comfortable

C3 makes it easy to generate D3-based charts by wrapping the code required to construct the entire chart. We don’t need to write D3 code any more.

Customizable

C3 gives some classes to each element when generating, so you can define a custom style by the class and it’s possible to extend the structure directly by D3.

Controllable

C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even if after it’s rendered.

In this guide, we are going to show you how to get started with C3.

1. Setup

Download the latest version here:

https://github.com/masayuki0812/c3/releases/latest

Installing by Bower/Component is also available with the name c3.

Then, load the scripts and css:

<!-- Load c3.css -->
<link href="/path/to/c3.css" rel="stylesheet" type="text/css">

<!-- Load d3.js and c3.js -->
<script src="/path/to/d3.v3.min.js" charset="utf-8"></script>
<script src="/path/to/c3.min.js"></script>

C3 depends on D3, so please load D3 too.

2. Generate Chart

C3 generates a chart by calling generate() with the argument object, and an element including the chart will insert into the element specified as a selector in that argument as bindto.

Prepare the element to bind the chart:

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

And, call generate() with arguments:

var chart = c3.generate({
    bindto: '#chart',
    data: {
      columns: [
        ['data1', 30, 200, 100, 400, 150, 250],
        ['data2', 50, 20, 10, 40, 15, 25]
      ]
    }
});

C3 supports the asynchronous module definition (AMD) API. If you use RequireJS, you can load like this:

require.config({
  baseUrl: '/js',
  paths: {
    d3: "http://d3js.org/d3.v3.min"
  }
});

require(["d3", "c3"], function(d3, c3) {
  c3.generate({
    ...
  });
});

Then, you will see the chart:
