-Matplotlib is a Python 2D plotting library which produces publication-quality
-figures in a variety of hardcopy formats and interactive environments across
-platforms. Matplotlib can be used in Python scripts, the Python and IPython
-shell (à la MATLAB or Mathematica), web application servers, and various
-graphical user interface toolkits.
 
-NOTE: The current master branch is now Python 3 only.  Python 2 support is
-being dropped.
+Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python.
