WD-XSL (which is what you're using) is always more trouble than it's
worth! XSLT is more trouble than it's worth if all you're using XSLT
for is a wrapper around JavaScript functions.

What XSLT is good at is transforming XML into another text-based
format, especially a different markup language. If you were creating
your pie charts in SVG, for example, then XSLT would be a good tool
for the job.

I was going to say "perfect" but unfortunately XPath doesn't have much
in the way of support for trigonometric functions, which you need in
order to create pie charts in SVG - implementing trigonometric
extension functions is a good use for JavaScript within XSLT (see
http://www.exslt.org/math/).

Cheers,

Jeni
