Log Message:
py-graphviz: updated to 0.19.1

Version 0.19.1

Fix undecoded CalledProcessError.stdout and .stderr when .pipe() call with an \ 
encoding different from self.encoding fails.

Fix missing project root conftest.py in source distribution.

Extend examples/graphviz-escapes.ipynb.

Improve test coverage.

Increase build scripts verbosity.

Version 0.19

Add PendingDeprecationWarning to calls using positional arguments that will be \ 
deprecated in a later version. The future API will allow from one to three \ 
positional arguments depending on the method or function. Keyword-only arguments \ 
where not around when this library was created. This signals dependents and in \ 
general users to start updating or pinning to the wanted version (or range). \ 
Crucially, this helps new users with a safer API that allows to avoid some \ 
common mistakes. Warnings reported in tests.

Add keyword-only outfile argument to .render() and stand-alone \ 
graphviz.render(). Allows to override the rendered output file name: \ 
.render(filename='spam.gv', outfile='spam.pdf') Allows to derive the format and \ 
the filename from the rendered outfile name: .render(outfile='spam.svg') Tries \ 
to infer default format from the outfile suffix. You can override by setting \ 
format explicitly. Warns with a graphviz.FormatSuffixMismatchWarning if there is \ 
a mismatch between given format and the inferred format from outfile suffix. \ 
Warns with a graphviz.UnknownSuffixWarning if format is given and outfile uses a \ 
suffix that cannot be mapped to a supported format.

Add graphviz.set_jupyter_format() to set the output format used by the Jupyter \ 
visualization of graphviz.Graph, graphviz.Digraph, and graphviz.Source \ 
(supported formats: 'svg', 'png', 'jpeg'). Replace _repr_svg_() internally with \ 
_repr_mimebundle_(include, exclude) returning a mimebundle {'image/svg+xml', \ 
'<?xml version=...'} by default. Adds support for \ 
IPython.display.display_png(). Adds support for IPython.display.display_jpeg().

Add keyword-only raise_if_result_exists argument to .render() and stand-alone \ 
graphviz.render(). Raises graphviz.FileExistsError if the rendered file already \ 
exists.

Add support to for .render() and stand-alone .render() to overwrite the input \ 
source file with the rendered output when using the outfile keyword-only \ 
argument. This probably only makes sense for text-based Graphviz formats such as \ 
dot or plain. You need to specify overwrite_filepath=True to enable this.

Add graphviz.CalledProcessError derived from subprocess.CalledProcessError so \ 
users can choose either one in their excepts.

Add graphviz.FileExistsError derived from FileExistsError so users can choose \ 
either one in their excepts.

Add --only-exe flag to run-tests.py (overrides --skip-exe).

Add --no-open and --open flags to build-docs.py.

Add lint-code.py and use in build job.

Increase doctest coverage.

Extend type annotations. Accept path-like objects for filename, directory, and \ 
filepath.

Extend and improve documentation.

Improve build tests.
