Need Help?? You should ask yourself...

• How do I post a question effectively? - ok, that's your data, what do you want to plot exactly?
• How do I compose an effective node title? - it's strange that you ask for 2d graphs when you have at least three coordinates...

On a general basis, for the plotting part, first decide what you're interested to plot, then take a look at GD::Graph and GD::Graph3D.

To read the data, you can open the file, then iterate on its lines - something like this:

   open my $fh, '<', $filename or die "open('$filename'): $!";
   while (<$fh>) {
      # Do whatever you want with the line in $_
   }
   close $fh;

Before going further, again, you must decide what you want to plot and how (e.g. you have three datasets: do you want a graph for each of them? Do you want to mix up all data? ...)
