G : graph A networkx graph pos : dictionary A dictionary with nodes as keys and positions as values. Positions should be sequences of length 2. edgelist : collection of edge tuples Draw only specified edges(default=G.edges()) width : float, or array of floats Line width of edges (default=1.0) edge_color : color string, or array of floats Edge color. Can be a single color format string (default='r'), or a sequence of colors with the same length as edgelist. If numeric values are specified they will be mapped to colors using the edge_cmap and edge_vmin,edge_vmax parameters. style : string Edge line style (default='solid') (solid|dashed|dotted,dashdot) alpha : float The edge transparency (default=1.0) edge_ cmap : Matplotlib colormap Colormap for mapping intensities of edges (default=None) edge_vmin,edge_vmax : floats Minimum and maximum for edge colormap scaling (default=None) ax : Matplotlib Axes object, optional Draw the graph in the specified Matplotlib axes. arrows : bool, optional (default=True) For directed graphs, if True draw arrowheads. Note: Arrows will be the same color as edges. arrowstyle : str, optional (default='-|>') For directed graphs, choose the style of the arrow heads. See :py:class: `matplotlib.patches.ArrowStyle` for more options. arrowsize : int, optional (default=10) For directed graphs, choose the size of the arrow head head's length and width.

G : graph A networkx graph pos : dictionary A dictionary with nodes as keys and positions as values. Positions should be sequences of length 2. ax : Matplotlib Axes object, optional Draw the graph in the specified Matplotlib axes. nodelist : list, optional Draw only specified nodes (default G.nodes()) node_size : scalar or array Size of nodes (default=300). If an array is specified it must be the same length as nodelist. node_color : color string, or array of floats Node color. Can be a single color format string (default='r'), or a sequence of colors with the same length as nodelist. If numeric values are specified they will be mapped to colors using the cmap and vmin,vmax parameters. See matplotlib.scatter for more details. node_shape : string The shape of the node. Specification is as matplotlib.scatter marker, one of 'so^>v<dph8' (default='o'). alpha : float or array of floats The node transparency. This can be a single alpha value (default=1.0), in which case it will be applied to all the nodes of color. Otherwise, if it is an array, the elements of alpha will be applied to the colors in order (cycling through alpha multiple times if necessary). cmap : Matplotlib colormap Colormap for mapping intensities of nodes (default=None) vmin,vmax : floats Minimum and maximum for node colormap scaling (default=None) linewidths : [None | scalar | sequence] Line width of symbol border (default =1.0) edgecolors : [None | scalar | sequence] Colors of node borders (default = node_color) label : [None| string] Label for legend
