In addition to these interfaces Veusz can be extended using plugins written in Python. The command interface is also usable by piping text into the program, allowing non-Python programs to use the program for plotting. As the saved file format for Veusz is a simple Python script containing commands which generate the plot, the user can easily switch back and forth between the GUI and module interfaces. Plots can be exported in several formats, including PDF, Postscript, SVG and EMF.ДЄlthough Veusz presents an easy-to-use graphical interface, it can also be used as a Python module for plotting, exposing the same object-oriented interface as seen in the GUI. Simple fitting of data can also be done within the program. Data analysis can be done within Veusz, by creating datasets can be linked to existing ones using Python expressions and in other ways. The program can read data from a number of sources, including text, CSV, HDF5 and FITS formats, and from external programs. The document can easily be manipulated in structure by rearranging the widgets. The appearance of the plot and what is plotted can be changed by modifying settings or formatting settings of these widgets. In Veusz, plots are built out of a number of widgets in a hierarchical, object-oriented manner.

It is implemented using PyQt and numpy, with some C++ extension modules for speed. Veusz is a multiplatform GUI scientific plotting package and plotting module written in Python, designed for publication-quality output.
