Perhaps more can be squeezed out of these graphs. For instance, one might use the same networks to determine where trade will shift if the major US ties are severed or capped at a certain size.
What the networks will miss, however, is the intensification of intra-country trade (so technically, self-ties in the represented graphs). In comparison to the EU, Canada is very lowly economically integrated between its 'sub-nodes' (provinces). Perhaps there's some potential there that the graph will fail to capture.
