Yes, they all morph into what is necessary to view the displayed data.
In your solution, it just says "iPlot" in the window titlebar, but the
tool can handle other types of data.

I think I have already solved this (see my follow-up posting), but you raise
an interesting question. Is there such thing as an appropriate iTool? Do
I need to know which iTool to use to open an ISV file? Can't I open
an ISV file with *any* iTool? Aren't all iTools really the same thing
underneath? (Since I can add an image to a volume, or a line to surface, etc.)

I tried that, and RESTORE restores some data, but it does not open an
iTool window and display the visualization.
After a little thought I realized that one it is possible to control the iTool
interface programmatically to execute the Open operation, so here is a simple
program to do that.
To use,
IDL> isv_open_kpb, isvfile
where isvfile is the name of the .isv file.
I make no guarantees, as my object-oriented programming is severely limited,
but this seems to work.
Plus, it *has* to be good luck to offer this up on Friday the 13th.
Cheers, Ken Bowman

What do you want to happen then, though? For the appropriate iTool to
start up and load that data set?

Actually, an ISV file is just a save file that contains a portion of
the iTools data/vis hierarchy. So you can just use restore.
