pYx

PyX is a Python package for the creation of PostScript, PDF, and SVG files. It provides a comprehensive set of drawing primitives and a high-level API for composing vector graphics with Python.

The library offers support for basic shapes and paths, transformations, colors, text rendering, and layout features such as layers and clipping. It includes TeX-based typesetting for mathematical notation, enabling precise mathematical labels in figures.

Typical usage involves constructing a canvas or figure, adding elements such as points, lines, curves, and text, and then exporting to PostScript, PDF, or SVG. PyX is designed to produce publication-quality graphics suitable for academic papers.

PyX is free and open-source software. It has a long-standing presence in the scientific Python ecosystem and is maintained by a community of volunteers.

It runs on major platforms where Python is available and aims to provide reliable vector rendering independent of a specific plotting backend, in contrast to more general-purpose plotting libraries. PyX is best known for fine-grained control over rendering and for its ability to incorporate LaTeX-friendly text and formulas into graphics.
