The advantage of GD::Graph is that it'd likely be rendered as a JPEG/ GIF, and that's something you can download and reuse in an executive chart. But if you want something interactive (think click-through), then Flash has that advantage.

I'e used Visual Engineering's KavaChart http://www.ve.com/kavachart/index.html/ to do 1, 2, 3, and 5 above. It may do 4, but I haven't tried anything like that with it. I have code for a simple System Load application listed at http://www.customvisuals.com/code.shtml. Look for System Load near the top of that page. You can also see something pulling data from a URL at http://www.customvisuals.com/ by viewing the source of that page. Check the graph on the left side of the page. Mike Schienle

Thanks for any information. For drawing graphs you can have a look at google graph api (http://code.google.com/apis/chart/) I've once used another cart libray offering API in different languages see : http://www.advsofteng.com/product.html And then there is GD::Graph, but I have no experience with this. For basic graphic functions look at Imager (imager.perl.org) -- Regards Rolf Schaufelberger

Thanks for any information. There are a lot of perl APIs built over various graphics packages. You can start with this list: http://search.cpan.org/modlist/Graphics You might also try searching cpan for some specific keywords, because I don't believe all the graphics modules are in that list. For example, I've used Image::Magick for doing some basic image resizing and conversion, but I don't see Image::Magick in that list. -- Jim Albert

Re: graphics in perl
Uhm, dude... a Perl module won't do that because Perl is a language, not a display technology. You're looking for something like Shockwave Flash. Though you can certainly have Perl generate everything. 2008/6/22 Malka Cymbalista [EMAIL PROTECTED]: We are running perl 5.8.5 on a Linux machine that is running apache 2.2.6 with mod_perl 2.0.3.
