Help! Any presentation graphics program in Debian Linux?

["W. Zabolotny" <wzab@ipe.pw.edu.pl>]

Hi!
I'd like to know if there is any good free application for preparing
of presentation graphics available in Debian distribution.
Such functions as bar charts, pie charts, scatter plots, line charts,
"whisker box" (for presentation os standard deviation) and so on are
necessary.
I'm just preparing small presentation about application of Linux in
digital signal processing. I wouldn't like to have to present
transparencies prepared with M$ PowerPoint...

If someone knows about such package, or could suggest another solution
(maybe a set of macros for Scilab, or Latex???) - please let me know.

                                        Thank you in advance
                                        Wojciech Zabolotny
                                        wzab@ipe.pw.edu.pl

PS. May be there is a need to write such a package? I'm considering
doing of it, after I finish my PhD thesis...
