Bug summary
importing matplotlib on a fresh Windows machine or container fails with the following traceback:
>>> import matplotlib

ImportError: DLL load failed while importing _path: The specified module could not be found.
AFAIK, the DLL that's being called for isn't displayed here but I suspect this is something from the MSVC runtime.
Code for reproduction
docker run -it python:3.11.1-windowsservercore-1809 powershell
pip install matplotlib
python
import matplotlib
Actual outcome

from matplotlib._path import (
ImportError: DLL load failed while importing _path: The specified module could not be found.
Expected outcome
matplotlib imports without errors.
Additional information
I think the MSVC runtime is currently a dependency of matplotlib and the required DLL should be distributed with the wheel. If I run pip install msvc-runtime the import works, maybe that package or something like it could be a transient OS-specific dependency.
