Veusz is a scientific plotting package written in Python. It uses PyQt
for display and user-interfaces, and numarray for handling the numeric
data. Veusz is designed to produce publication-ready Postscript

Veusz provides a GUI, command line and scripting interface (based on
Python) to its plotting facilities. The plots are built using an
object-based system to provide a consistent interface.
