Many Matplotlib plots support arrays as input and in particular, they support NumPy arrays. The NumPy library is the most widely-supported means for supporting numeric arrays in Python.

The project was initiated by John D. Hunter in 2008. The initial introductory text stated: "Matplotlib is a library for making 2D plots of arrays in Python. Although it has its origins in emulating ...

In this course, you will learn to use Matplotlib to plot data in Python. You will learn to produce several types of plot, how to arrange multiple plots into an array of subplots, and how to save plots ...

We use matplotlib for plotting in python. We also have to convert SymPy matrices to NumPy arrays prior to plotting. Therefore, we prefer to define vectors as NumPy arrays if we intend to just plot ...

Arrays are super useful. If you want even more details about python and arrays - this is a very useful site from Cornell. My python-foo will probably never catch up with The Virtuosi.
