But why use Wordle at all if it doesn't behave as required?  The
functionality would not be very difficult to duplicate.

I have been looking at the production of accessible Tag Clouds/Tag
Wedges for a while now[1].  I started off using an XHTML/CSS rendering
but have since considered what to do when a raster graphic output format
is a requirement.  This would be achieved by first rendering the output
as SVG, then use readily available, Open Source tools to convert to
JPEG/PNG, etc  OR to XHTML+CSS.  XSLT is your friend...

Recent work for a client on an XHTML/CSS version has an option to render
statistics in the code - much like Tanguy's example although my code
displays frequencies rather than percentages.

Although the article I have referenced talks about PHP, my regular work
is in Perl.  'Fancy' graphics stuff would be achieved using GD or
ImageMagick.  I feel that running the creation/rendering server-side can
only make the application more accessible as it requires less of the
client end - and could indeed even work in a text user agent such as
Lynx (output graphics would be downloadable.)

Cheers
