WP-D3 (Text Mode) and Persistent Paragraph Tags

Hello,

I’ve used WP-D3 many times and it’s probably my favorite plugin. However, I’m trying to insert an interactive Sankey chart into a WordPress page and am having some trouble figuring out why WP-D3 and my site are no longer on friendly terms: WordPress is inserting unwanted paragraph tags and breaks </br> throughout my JavaScript.

The WP-D3 has an interface for Visual Mode, but I create all of my posts in Text Mode (it makes editing in IE easier and I’ve found it helps me prevent WP from inserting unwanted tags into my html and javascript content). I’ve used Text Mode in the past with success with D3 and NVD3. This situation has stumped me and I’m not sure if I’ve just overlooked something trivial or if there’s something more complicated going on.

Any solutions or suggestions that can point me in the right direction are very much appreciated!

Here’s the page: http://www.d8aism.com/?page_id=702

Here’s what I’ve attempted in terms of troubleshooting:

1. Checked the JavaScript for accuracy (it was created with RCharts and tested on my PC)

2. Confirmed that the JavaScript files (d3.js and Sankey.js) are being called from the Media Library and that the element tags are listed between the [d3-link] tags.

3. Confirmed that all of the JavaScript code, copied directly from the RCharts template, is inserted between the [d3-source] tags.

4. Confirmed that the <div> tag reference name matches the params element name (i.e., [d3-source canvas=”sankey1″] )

5. Confirmed that the Raw HTML plugin’s “Disable automatic paragraphs” box is checked and that the wpautopop filter is removed from the content in the theme’s functions.php file.

remove_filter( ‘the_content’, ‘wpautop’ );
remove_filter( ‘the_excerpt’, ‘wpautop’ );

In the interest of completeness, here is the full page content:
