IRIS Explorer

    Numerical Algorithms Group (NAG)'s tool
   for developing visualisation applications via a visual
   programming environment.  IRIS Explorer has a range of
   visualisation techniques, from simple graphs to
   multidimensional animation, that can help show trends and
   relationships in data.

   IRIS Explorer uses standard Open Inventor, ImageVision and
   OpenGL libraries as well as NAG's own numerical libraries.
   It is available for Windows, Unix and Linux.  It has a
   point-and-click interface and a library of "modules" (software
   routines).
