Either this module or nx_agraph can be used to interface with graphviz. Examples -------- >>> G = nx.complete_graph(5) >>> PG = nx.nx_pydot.to_pydot(G) >>> H = nx.nx_pydot.from_pydot(PG) See Also -------- - pydot: https://github.com/erocarrera/pydot - Graphviz: https://www.graphviz.org - DOT Language: http://www.graphviz.org/doc/info/lang.html N)getpreferredencoding) open_file) write_dotread_dotgraphviz_layout pydot_layoutto_pydot from_pydotw)modecCs.d}tj|tddt|}||dS)zgWrite NetworkX graph G to Graphviz dot format on path.

If this file contains multiple graphs, only the first such graph is returned. All graphs _except_ the first are silently ignored. Parameters ---------- path : str or file Filename or file handle. Returns ------- G : MultiGraph or MultiDiGraph A :class:`MultiGraph` or :class:`MultiDiGraph`. Notes ----- Use `G = nx.Graph(nx.nx_pydot.read_dot(path))` to return a :class:`Graph` instead of a :class:`MultiGraph`. rNznx.nx_pydot.read_dot depends on the pydot package, which hasknown issues and is not actively maintained.

Returns a dictionary of positions keyed by node. Parameters ---------- G : NetworkX Graph The graph for which the layout is computed. prog : string (default: 'neato') The name of the GraphViz program to use for layout. Options depend on GraphViz version but may include: 'dot', 'twopi', 'fdp', 'sfdp', 'circo' root : Node from G or None (default: None) The node of G from which to start some layout algorithms. Returns ------- Dictionary of (x, y) positions keyed by node. Examples -------- >>> G = nx.complete_graph(4) >>> pos = nx.nx_pydot.graphviz_layout(G) >>> pos = nx.nx_pydot.graphviz_layout(G, prog="dot") Notes ----- This is a wrapper for pydot_layout. znx.nx_pydot.graphviz_layout depends on the pydot package, which hasknown issues and is not actively maintained.

Examples -------- >>> G = nx.complete_graph(4) >>> pos = nx.nx_pydot.pydot_layout(G) >>> pos = nx.nx_pydot.pydot_layout(G, prog="dot") Notes ----- If you use complex node objects, they may have the same string representation and GraphViz could treat them as the same node. The layout may assign both nodes a single location. See Issue #1568 If this occurs in your case, consider relabeling the nodes just for the layout computation using something similar to:: H = nx.convert_node_labels_to_integers(G, label_attribute='node_label') H_layout = nx.nx_pydot.pydot_layout(G, prog='dot') G_layout = {H.nodes[n]['node_label']: p for n, p in H_layout.items()} rNznx.nx_pydot.pydot_layout depends on the pydot package, which hasknown issues and is not actively maintained.
