Draw the graph G with matplotlib (pylab).
This is a pylab friendly function that will use the
current pylab figure axes (e.g. subplot).
pos is a dictionary keyed by vertex with a two-tuple
of x-y positions as the value.
See networkx.layout for functions that compute node positions.
Usage:
>>> from networkx import *
>>> G=dodecahedral_graph()
>>> draw(G)
>>> pos=graphviz_layout(G)
>>> draw(G,pos)
>>> draw(G,pos=spring_layout(G))
Also see doc/examples/draw_*
| Parameters: |
- nodelist: list of nodes to be drawn (default=G.nodes())
- edgelist: list of edges to be drawn (default=G.edges())
- node_size: scalar or array of the same length as nodelist (default=300)
- node_color: single color string or numeric/numarray array of floats (default=’r’)
- node_shape: node shape (default=’o’), or ‘so^>v<dph8’ see pylab.scatter
- alpha: transparency (default=1.0)
- cmap: colormap for mapping intensities (default=None)
- vmin,vmax: min and max for colormap scaling (default=None)
- width: line width of edges (default =1.0)
- edge_color: scalar or array (default=’k’)
- edge_cmap: colormap for edge intensities (default=None)
- edge_vmin,edge_vmax: min and max for colormap edge scaling (default=None)
- style: edge linestyle (default=’solid’) (solid|dashed|dotted,dashdot)
- labels: dictionary keyed by node of text labels (default=None)
- font_size: size for text labels (default=12)
- font_color: (default=’k’)
- font_weight: (default=’normal’)
- font_family: (default=’sans-serif’)
- ax: matplotlib axes instance

NB: this has the same name as pylab.draw so beware when using
>>> from networkx import *
since you will overwrite the pylab.draw function.
A good alternative is to use
>>> import pylab as P
>>> import networkx as NX
>>> G=NX.dodecahedral_graph()
and then use
>>> NX.draw(G) # networkx draw()
and
>>> P.draw() # pylab draw()
