Missing dependency: matplotlib

[aron-bram]

Matplotlib seems to be missing from the list of dependencies.

As I got the following error after installing the package and trying to use it.

Traceback (most recent call last):

ModuleNotFoundError: No module named 'matplotlib'

Shouldn't it be added to pyproject.toml dependencies?
