Veusz

Veusz provides a graphical interface for creating publication‑ready two‑dimensional and three‑dimensional scientific plots. Users assemble plots by adding and configuring a hierarchy of widgets, allowing fine‑grained control over visual properties while keeping the workflow consistent across different plot types. The application can also be invoked as a Python module, enabling script‑based generation of figures.

The program runs on Windows, Linux/Unix and macOS and supports a range of output formats, including vector graphics such as PDF, Postscript, SVG and EMF, as well as bitmap images. Data can be imported from plain text, CSV, HDF5 and FITS files, and users may define or transform datasets within the interface using mathematical expressions. Extensions are possible through plugins that add new importers, manipulation tools or automation capabilities.

Veusz is free software aimed at both novice and experienced users who need flexible, high‑quality scientific visualisation. Its object‑based design, cross‑platform availability and support for both interactive and programmatic use make it suitable for research, teaching and technical publishing.
