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!.

Cloudstitch is a community of spreadsheet powered widgets you can add to any site — things like product lists, data visualizations, and conference schedules.
This plugin makes every widget on Cloudstitch available in WordPress with a simple Shortcode.
Adding a shaded electoral map of the US, for example, is as simple as adding the following line: <code>[cloudstitch widget="project-templates/electoral-map-visualization"]</code>
<h3>Trying it Out</h3>
Try out the plugin by injecting demo widget already on Cloudstitch. Just add the following Shortcode to a page or post:
<pre><code>`
</code></pre>
[cloudstitch widget=”project-templates/electoral-map-visualization”] 
 `
<h3>Using your own Cloudstitch Widgets</h3>
You can inject any widget that you’ve duplicated and customized on Cloudstitch. The general Shortcode format is:
<pre><code>`
</code></pre>
[cloudstitch widget=”USER-NAME/PROJECT-NAME”] 
 `
For example, let’s say you visited Cloudstitch.io and duplicated <a href="http://cloudstitch.io/project-templates/electoral-map-visualization" rel="nofollow ugc">that electoral map widget</a>.
Assuming your username is <code>TheIncredibleHulk</code>, you would end up with your own copy of the project hosted at a URL like this: <code>http://cloudstitch.io/TheIncredibleHulk/electoral-map-visualization</code>.
Your custom Shortcode is thus <code>[cloudstitch widget="TheIncredibleHulk/electoral-map-visualization"]</code>
