### Example 1 ####

G.add_edge('a',2)
G.add_edge(2,'c')
G.add_edge('a','c',0,{'dash':(2,2)})
G.add_edge('a','c',1)
G.add_edge('a',4)
G.add_edge(4,'c')
G.add_edge('out','c',0,{'fill':'red', 'width':3})
G.add_edge('c','d')

# Growth edges
G.add_edge('out',11)

G.add_edge('out',12,2)
G.add_edge('out',12,3)

# Some example TkPassthrough options
G.node['a']['fill'] = 'white'
G.node['a']['dash'] = (2,2)

### Filter example
for n in G.nodes_iter():
    G.node[n]['real'] = True

# Now we're going to add a couple of "fake" nodes; IE, nodes
#  that should be not be displayed because they are not in the filter.
#  If they do show up, they'll cause us to fail some of the base checks
G.add_edge('out','fake1')
G.add_edge('a','fake2')
G.add_edge('qqqq','fake3')
G.add_edge('fake3','fake4')
G.add_node('fake_alone')
