  Not directly, but we could add "vector output" support at some point.  The 
current output support outputs images which are based on pixmaps - that is, 
they are bitmap images and not vector images.  We could add a vector output 
subsystem.  Please file a feature request at http://bugs.kde.org/ .

  You can implement much of this with a data plugin in Kst.

   That would be great.  You could easily write a Kst datasource plugin for

   We might have a Windows compatible version in KDE 4 timeframe.
