nxpd is a Python package for visualizing NetworkX graphs using pydot
and graphviz. Support is also provided for inline displays within IPython
notebooks.
Installation is easy:
pip install nxpd
Alternatively, you can use git:
git clone https://github.com/chebee7i/nxpd
Then, move into the nxpd directory and install the old fashioned way:
python setup.py install
Basic usage is as follows:
import networkx as nx
from nxpd import draw
G = nx.cycle_graph(4, create_using=nx.DiGraph())
draw(G)
This will display a PNG (by default) using your operating system's default
PNG viewer. Alternatively, if you are in an IPython notebook, then you
might like the image displayed inline. This is achieved by setting the show
parameter of the draw function.
draw(G, show='ipynb')
If you want all graphs to be drawn inline, then you can set a global parameter.
from nxpd import nxpdParams
nxpdParams['show'] = 'ipynb'
draw(G)
Any graph/node/edge attribute that is supported by DOT is passed through to graphviz (via pydot). All others are skipped.
G = nx.DiGraph()
G.graph['rankdir'] = 'LR'
G.graph['dpi'] = 120
G.add_cycle(range(4))
G.add_node(0, color='red', style='filled', fillcolor='pink')
G.add_node(1, shape='square')
G.add_node(3, style='filled', fillcolor='#00ffff')
G.add_edge(0, 1, color='red', style='dashed')
G.add_edge(3, 3, label='a')
draw(G)
