Description: Auto-instantiating a Figure seems reasonable enough, and helps with GUI builders. (The auto-instantiated figure must be a plain Figure(), not a a pyplot-registered figure, both because most likely one should not use pyplot when building GUIs, and also more prosaically because that would run into a circular dependency (pyplot needs a canvas already instantiated (actually a manager that holds a canvas) to store into its global registry). Closes #17349. PR Summary PR Checklist Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (run flake8 on changed files to check). New features are documented, with examples if plot related. Documentation is sphinx and numpydoc compliant (the docs should build without error). Conforms to Matplotlib style conventions (install flake8-docstrings and pydocstyle<4 and run flake8 --docstring-convention=all). New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there). API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there).
