%h2.text-center Why C3?
.row.text-center.features
.medium-4.large-4.columns.supporticons
%h3 Comfortable
%p
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.
.medium-4.large-4.columns.supporticons
%h3 Customizable
%p
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.
.medium-4.large-4.columns.supporticons
%h3 Controllable
%p
C3 provides a variety of APIs and callbacks to access the state of the chart. By using them, you can update the chart even after it's rendered.
%h3.text-center.sub
C3 enables deeper integration of charts into your application.

%h3 Browser Support
%p Because of the dependence on D3, C3 supports only modern browsers D3 supports. Please see <a href="https://github.com/mbostock/d3/wiki#browser--platform-support">the description in D3</a>.
%p Note: For IE9 and IE10, polyfill is required because c3 uses <span class="code">MutationObserver</span>, which is not supported in those versions. However, it's not required if charts always will be binded to the DOM specified by <span class="code">bindto</span> because <span class="code">MutationObserver</span> is not called in that case.
%h3 Dependency
%ul
%li <a href="https://github.com/mbostock/d3" target="_blank">D3.js</a> <span class="code">^4.12.0</span>
%p Note: If you need to use D3 v3.x, please use C3 <a href="https://unpkg.com/c3@0.4.22/c3.js">v0.4.22</a>, which is compatible with D3 v3.x.
