Matplotlib is a free Python library for creating static, animated, and interactive visualizations. The project says it can make publication-quality plots, and interactive figures can support zooming, panning, and updates. Users can customize visual style and figure layout, then export figures to many file formats. Matplotlib can be embedded in JupyterLab and graphical user interfaces. Third-party packages built on it include seaborn, HoloViews, plotnine, Cartopy, and WCSAxes. Official release wheels are available for Linux, macOS, and Windows, while documented runtime dependencies require Python 3.11 or newer. Additional dependencies may be needed for other GUI frameworks, LaTeX rendering, animation saving, and more file formats. The project describes its code as BSD-compatible and grants a royalty-free license subject to its license terms. Community help is available through Discourse, GitHub issues, and Stack Overflow. The project says Matplotlib began as a tool for EEG data and is now used in many fields. Its listed plan is Matplotlib at free.
