Veusz is a scientific plotting package. It is designed to produce publication-ready PDF or SVG output. Graphs are built-up by combining plotting widgets. The user interface aims to be simple, consistent and powerful.
Veusz provides GUI, Python module, command line, scripting, DBUS and SAMP interfaces to its plotting facilities. It also allows for manipulation and editing of datasets. Data can be captured from external sources such as Internet sockets or other programs.
