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).
