Jonathan, great to see this new tool.

If you are able to introduce the concept of groups (e.g. north america consists of Canada, Mexico & USA) then it would be easy for you to build a new group based on whatever criteria you want.

Can the graphics resize to fill the screen? Also on my monitor (1680 x 1050) the icon for consumption, production & import/export fits only the top right of the axis leaving a lot of white space "within" the graph.

Ukraine & Uzbekistan seem to have taken over Russia on the map! a small buglet i think.

It would be nice to see all the countries (whole globe) coloured in by exporter or importer.

You'll get your colored globe eventually -- it's part of the plan to allow groups of nations.

And the new ex-Soviet republics do present a problem for me. The code I'm using for maps (the R maps pacakge) does not have the post-USSR national boundaries. I have to do some searching to see if anyone has an add-on for R that willl draw Kazakhstan, etc.

For full screen plots you just need to click on the image. This will download a .pdf file that you can rescale to any size you want and, perhaps more importantly, prints out very nicely and can be embedded in documents.
