How do I install matplotlib in Python?

The standard way to install matplotlib is by running `python -m pip install matplotlib`. If you are using Anaconda, use `conda install -c conda-forge matplotlib`.

Why causes the 'No module named matplotlib' error?

This error occurs when the python interpreter cannot locate the `matplotlib` package. It is often caused by missing installation or environment mismatch (e.g. installing in global but running in venv).
