Is there a common data format for this data? Climate data files, which 
are a bit similar, are often huge (>100MB) NetCDF files. There are 
libraries for reading NetCDF files, which have Perl interfaces, but for 
visualization the data would need to be rendered onto something that can 
be put to screen.

Yes, putting simple matrix data simply onto a Gdk Pixbuf is fast and 
simple, but if you want to do fancier visualization than that, there are 
OpenGL and VTK (which is news to me also) and other tools to look at. 
But it doesn't matter how complicated it is, if the end product is a Gdk 
Pixbuf, you can use it simply in you Gtk2-Perl code. BTW, VTK homepage 
says it has interfaces to Tcl/Tk, Java, and Python, i.e., Perl is not 
mentioned. Should I be worried that I see more often Python than Perl 
mentioned in these kinds of situations?
