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.)
