Matplotlib is an open-source visualization library for the Python programming language, widely used for creating static, animated and interactive plots. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, Qt, GTK and wxPython. It offers a variety of plotting functionalities, including line plots, bar charts, histograms, scatter plots and 3D visualizations. Created by John D. Hunter in 2003, Matplotlib has become a fundamental tool for data visualization in Python, extensively used by data scientists, researchers and engineers worldwide.
