Description
Hello,
I am trying to use matplotnode on a docker container but I am getting this exception when a try to save the image. I don't need to show the graphic, only save the image.
```
Exception _tkinter.TclError: 'no display name and no $DISPLAY environment variable' in ignored
```

Research direction
Start by reproducing the image-save operation in the Docker container and inspect how matplotnode initializes matplotlib through the CPython API. Confirm the headless save path works without a DISPLAY variable and that the TclError no longer appears.
