These visualization projects are interesting, in particular as far as 
octaviz is concerned since vtk is a very powerful software. However, 
I don't think we should abandon gnuplot totally. It has a large user 
base, can really do a lot of things and is highly portable. Its 
developpers' team is really active (see the changelog
in the cvs [www.gnuplot.info] to be convinced) 
and is working on interesting features. One of the last feature that was
lacking is custom colors, and it is now implemented in cvs, as John W. Eaton
said in an earlier mail.

Personnally, I'm working on a new interactive terminal for gnuplot, 
based on the wxwidgets toolkit. It aims at being totally cross-platform 
and more user-friendly (font anti-aliasing, toolbar for interactive 
action on the plot, menus to access quickly to different settings). I 
received good support and help from the current developping team.

On the other hand, I'm totally in favor of an abstraction layer between 
octave and the program used to plot. But, if I remember well, it has 
already been discussed and is a work-in-progress.

Of course, thanks to gnuplot ! You just have to choose the svg terminal, 
with the command "set terminal svg". You can send this command with 
__gnuplot_set__. Then, it's up to you to open the plot in inkscape for 
example to add details on the plot.
