D3.js Sample: A Pie Chart

The following Pie Chart, drawn by D3.js library:

Using our plugin, named Blazing Charts, I added the following shortcode to this post:

(left-bracket)BlazingChart charttype="d3" source="d3-js-sample-pie" options="pie"(right bracket)

The first parameter specifies which charting library is used. The second parameter is the slug of a Custom Post Type, named Chart Snippets, introduced by that plugin. The third parameter can be a comma-separated list of auxiliary libraries loaded after the main one. For drawing pie charts, D3pie.js should also be loaded.

The source of the script for the drawing is added as plain text to a Chart Snippet. The content of the chart snippet for the above chart is as following:
