Well, after some googling I found a suitable hack to embed the SVG.

I took a look at the way Tobias Reif is serving his SVG on
http://www.pinkjuice.com/howto/rubysvg/

The only hack that works well (for me) is to write a ruby file which when
executed forces the content-type to "image/svg+xml" and writes out the SVG
graph. So I dynamically create this ruby file and then point to it as the
data source for the object tag.

<object type="image/svg+xml" data="/rails/chart_svg.cgi?IEHack=.svg"
width="800" height="600"></object>

In my case, with rails and my setup, I had to make the ruby file have a .cgi
extension to make it executable.

This works very well, and is much more palatable compared to my previous
hack of keeping a static html page pointing at the SVG file.
