1. Add `bin/get_size.py` so that `python bin/get_size.py plotly build`
 reports the number of files and total size in bytes of the `plotly`
 directory (where generated code is put) and the `build` directory
 that is populated by `python setup.py build`.
1. Modify `codegen/__init__.py` and `./setup.py` so that
 `python setup.py --reformat=false` disables reformatting.
1. Assign an empty string to the `data_docs` field of generated
 validators. (This has a major impact because those docs are
 duplicated many times.)
1. Alias name of base validator during import in
 `codegen/validators.py`.
1. Remove the long list of CSS colors from help strings for color
 properties.
1. Replace `super(Parent, self)` with `super()` in generated code.
1. Drop use of sys.version_info and TYPE_CHECKING. Removed the check
 for Python < 3.7 using `sys.version_info` and as a backup checking
 `typing.TYPE_CHECKING`; this saves a little space and also cleans
 up the code.
1. Remove mention of Chart Studio and explicit enumeration of system
 font names from plotly.js / plot-schema.json so that this text
 isn't copied dozens of times into the plotly.py bundle.
1. Introduce `_init_provided()` for `BaseFigure` and `BasePlotlyType`
 that calls a helper function `_initialize_provided()` to replace
 repetitions of:
```
_v = arg.pop("something", None)
_v = something if something is not None else _v
if _v is not None:
 self["something"] = _v
```
Original size of plotly/**/*.py: 42283582 bytes
Current size of plotly/**/*.py: 31931739 bytes
Change: -25%

1. Add `from __future__ import annotations` as the first line of
 generated files so that modern Python type annotation syntax can
 be used in older versions of Python.
1. Add `from typing import Any` and `from numpy.types import NDArray`
 to all generated files rather than trying to figure out which
 of these imports are needed on a file-by-file basis.
1. Rename `get_typing_type` in `codegen/datatypes.py` to
 `get_python_type` to make purpose clearer.
1. Add additional optional parameter to `get_python_type` so that
 `compound` and `compound_array` types in the schema are converted
 to `None` rather than causing an exception.
1. Modify `codegen/datatypes.py` to add type annotations to constructor
 parameters.
1. Modify `codegen/figure.py` to add `bool` type to one figure
 constructor parameter.
FIXME: figure out what type should actually be returned for `compound`
and `compound_array`.
FIXME: figure out what types to use for other standard parameters of
figures generated by `codegen/figure.py`.

1. Modify `commands.py` to run code generation.
1. Remove comments from generated code.
1. Replaced named arguments in constructors with positional arguments.
1. Regenerate all code.
Notes:
The generated code is reformatted once again: this slightly increases
size but makes it more readable.
There is one flaky test:
`tests/test_plotly_utils/validators/test_colorscale_validator.py::test_acceptance_named[Inferno_r]`
It fails when the entire test suite is run but does *not* fail when
only `test_colorscale_validator.py` is run (using Python 3.11.9).

1. Update required version of `black` in `pyproject.toml` and `.circleci/config.yml`.
2. Update Python version identifiers in `tool.black` section of `pyproject.toml` to include `py311` and `py312`.
3. Modify invocation of `black` in `commands.py` to format with `py311`.
4. Regenerate and reformat code.
