Matplotlib

Matplotlib was originally written by John D. Hunter. Since then it has had an active development community and is distributed under a BSD-style license. Michael Droettboom was nominated as Matplotlib's lead developer shortly before John Hunter's death in August 2012 and was further joined by Thomas Caswell. Matplotlib is a NumFOCUS fiscally sponsored project.

Usage

Matplotlib is used in scientific research as a tool for data visualization. For example, the Event Horizon Telescope collaboration used Matplotlib to produce visualizations during the effort to create the first image of a black hole. Matplotlib also underpins the plotting functionality of many scientific Python libraries (for instance, pandas uses Matplotlib as its default backend for plotting). Its importance to the scientific community has been acknowledged by institutions such as NASA, which in 2024 awarded a grant to support Matplotlib’s continued development as part of an initiative to fund widely used open-source scientific software.

In education and data science, Matplotlib is frequently used to teach programming and data visualization. It integrates with Jupyter Notebook, allowing students and instructors to generate inline plots and interactively explore data within a notebook environment. Many educational institutions incorporate Matplotlib into their curricula for teaching STEM concepts, and it is widely featured in tutorials, workshops, and open online courses as a primary plotting library.
