| 260 | Parameters |
| 261 | ---------- |
| 262 | filename : str or None, optional |
| 263 | The name of the file to write to disk. If the provided `filename` |
| 264 | doesn't include an extension, '.png' will be used by default. |
| 265 | If `filename` is None, no file will be written, and we communicate |
| 266 | with dot using only pipes. |
| 267 | format : {'png', 'pdf', 'dot', 'svg', 'jpeg', 'jpg'}, optional |
| 268 | Format in which to write output file. Default is 'png'. |
| 269 | optimize_graph : bool, optional |
| 270 | If True, the graph is optimized before rendering. Otherwise, |
| 271 | the graph is displayed as is. Default is False. |
| 272 | color: {None, 'order'}, optional |
| 273 | Options to color nodes. Provide ``cmap=`` keyword for additional |
| 274 | colormap |
| 275 | **kwargs |
| 276 | Additional keyword arguments to forward to ``to_graphviz``. |
| 277 | |
| 278 | Examples |
