Tools for Visulisation

in Python


Matplotlib is a plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits... designed to closely resemble that of MATLAB, though its use is discouraged. SciPy makes use of Matplotlib.


... Matplotlib has pledged to not support Python 2 past 2020 by signing the Python 3 Statement.
