Args: format: The output format used for rendering (``'pdf'``, ``'png'``, etc.). renderer: The output renderer used for rendering (``'cairo'``, ``'gd'``, ...). formatter: The output formatter used for rendering (``'cairo'``, ``'gd'``, ...). neato_no_op: Neato layout engine no-op flag. quiet (bool): Suppress ``stderr`` output from the layout subprocess. engine: Layout engine for rendering (``'dot'``, ``'neato'``, ...). encoding: Encoding for decoding the stdout. Returns: Bytes or if encoding is given decoded string (stdout of the layout command). Raises: ValueError: If ``engine``, ``format``, ``renderer``, or ``formatter`` are unknown. graphviz.RequiredArgumentError: If ``formatter`` is given but ``renderer`` is None. graphviz.ExecutableNotFound: If the Graphviz ``dot`` executable is not found. graphviz.CalledProcessError: If the returncode (exit status) of the rendering ``dot`` subprocess is non-zero.
