Well, it turns out I was too curious myself already, so I checked a bit 
further.

I found the original mailinglist thread [1] and the missing patch to 
enable the jqplot alternatives for most of our chart types. Due to the 
age of the patch there were a few issues, but with some tweaking I 
managed to get it to work again. I like the result so much better than 
the old goffice based charts that I have chosen to remove the goffice 
based ones.

The old list thread also pointed at some issues with the jqplot charts. 
I think I have fixed most of them, except the labels running over one 
another if there are lots of data points. If any other issues pop up, 
please let me know.

And a random list of things that should/could be done still:
- remove the gog code (should)
- labels running over one another if there are many data points
- dynamic sizing as an alternative option to the fixed width/height we 
now have to specify
- some more code optimizations, like
   * linking to minimized versions of the js files
   * drop some unused/invalid chart options (in js code that is)
- add/improve interaction to the charts

Most of these are minor tweaks. Even as they are now, the jquery based 
charts are ready for feature freeze, IMO.
