    Have trade data for 30 countries. Want to graph out the linkages of 30 countries to their top trading partners and "compare" the linkages (e.g. "thickness" of linkages, "shading" of linkages)

    Any all recommendations welcome - thx

    You could try the classical flow map http://en.wikipedia.org/wiki/Flow_map

    Here you can see better examples:

    If the result is too confusing (overlaping flows, countries too close, ... ) you could abstract it to a graph. I recently tested Gephi (http://gephi.org/) and its quite simple to get a good graph from node and edge data.
