Matplotlib
Matplotlib is a Python plotting library that enables the creation of static, interactive, and animated visualizations, and integrates well with NumPy and other scientific libraries. It offers both an object-oriented API and a MATLAB-like procedural interface, though the latter is now discouraged. Originally created by John D. Hunter, Matplotlib is maintained by an active community and is widely used in scientific research, education, and data science, including high-profile projects like the Event Horizon Telescope. The library is freely available under a BSD-style license and continues to receive institutional support and recognition for its role in open-source scientific software.
