 Networkx provides tools to attach data to nodes and edges; in the above
 example you can see that asciigraf uses this to attach a ``Point``
 object to each node indicating where on the *(x, y)* plane each node
-starts ( *0,0* is at the top-left).
+starts ( *0,0* is at the top-left). It also attaches a ``length`` attribute
+to each edge which matches the number of characters in that edge.
