[Matplotlib-users] Graphs - another question

[G. S. <g....@po...>]

One further question.
I'm trying to construct a particular category of graphs. 
I need to establish not only edges between nodes, but also edges between
edges and nodes. 

.-----.
(edge between nodes)

        |

        |
(edge between a node and an edge)

Do you know how can I represent this graphs through python, in
particular using network? Is it possible? Many thanks.
All the best,
nico
