CodeFlower works in Chrome but not in IE 9

Hello again.
I did some research and the consensus is that D3.js should work in IE9 and up. However, when I tried the CodeFlower in IE9 it gave me the following errors:

> SCRIPT5009: 'CSSStyleDeclaration' is undefined
> d3.js, line 7 character 3
> SCRIPT5009: 'd3' is undefined
> d3.geom.js, line 1 character 13
> SCRIPT5009: 'd3' is undefined
> d3.layout.js, line 1 character 13
> SCRIPT5009: 'd3' is undefined
> asdbsw01poc.fmr.com:801, line 144 character 7

Chrome did not have any errors.
I am wondering if this is purely a D3 thing or if any modifications could be made that would fix this problem. I would really like to make the diagram visible to those using IE. Perhaps an update of your D3 file would fix this issue?
Please help and thank you in advance.
