প্যারামিটার

• filename (str) -- file path to save image to.

• style (dict) -- keys are the pass classes and the values are the colors to make them. An example can be seen in the DEFAULT_STYLE. An ordered dict can be used to ensure a priority coloring when pass falls into multiple categories. Any values not included in the provided dict will be filled in from the default dict.

• raw (bool) -- If True, save the raw Dot output instead of the image.
