By default, this package supports only non-interactive graphics output.
For interactive graphics, install:

- gtk+3 gir-freedesktop python3-gobject python3-cairocffi
  (for GTK3Agg/GTK3Cairo backend)
- python3-PyQt5-svg (for Qt5Agg backend)
- python3-tkinter (for TkAgg backend)
- python3-tornado (for webagg backend)

The backend can be defined in $XDG_CONFIG_HOME/matplotlib/matplotlibrc

Matplotlib’s LaTeX support requires a working LaTeX installation and
ghostscript.
