D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.
Ths plugin provides the current last version of D3 (v3.3) and a javascript editor to add javascript code into your post or pages and render it. 
All extra .css or .js files can be uploaded to your WordPress blog and then included into the post/page easily using built-in functions. 
Enjoy!.
