I'm a PDL non-user who will probably become a user at some point, and as
such am also interested in clear docs for beginners.

Is this correct?

These modules are now part of the current PDL distribution packages, and
should be available on supported platforms:
 - PDL::Graphics::Gnuplot
 - PDL::Graphics::Prima
 - PDL::Graphics::Simple

PDL graphics modules can be divided into "static plotting" and "dynamic
plotting". The difference, is that static plots show a snapshot of your
data, whereas dynamic plots refresh themselves to show changes to the data.

PDL::Graphics::Gnuplot is a static graphing module, PDL::Graphics::Prima is
a dynamic graphing module.

PDL::Graphics::Simple is a unified front end for various static graphing
modules that have proved useful with PDL, and it knows to search for
whichever are installed on your system.

Question: I've read good things about a "TriD" plotting package, which
(among other things) lets you rotate & zoom the a 3d plot with the mouse.
Which class is that package, static or dynamic? I'd guess that allowing
mouse manipulations doesn't make it dynamic, but if the 3d plot changes as
the data changes, it is dynamic.

Thanks
