Use MultiNet. It will take a minute or two at most, depending on your
CPU speed and how much memory your machine has --  not hours. It will
let you decide which three dimensions you want to see, to rotate, zoom,
or pan at will. It will let you use he eigenvector coordinates as a new
variable in any subsequent analysis, and it will let you relate any node
characteristics/variables to the network's structure. It always gives
you a graphic representation of anything it does. Write to Andrew Seary
([log in to unmask]) for more details on how you can use it for two-mode analysis.
