Wonderful tool - thanks a lot.
My suggestion would be to also have aggregated totals and graphs, say the Middle East, Europe outside Russia, etc

Although BP provides regional totals, I want a little more flexibility. In a future version I'd like to allow users to select any combination of countries they want. "North America" is a fine grouping, but how about "English Speaking Nations" or BRIC or Commonwealth, etc.? And you'd want to see each country in the group colored by import/export. That's the plan at the moment.

Terrific.
Presumably it is part of your plan, but I would like to put a plea in that obvious and often used groups like the EU should be one-click accessible rather than needing to be created as a group - just thought I would clarify!

I'm in total agreement. The only reason I didn't include the groupings that BP has in their dataset is that I'd like to show which members of the group are importers and which are exporters instead of just coloring the entire block either red or green.

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.

An interesting grouping would be "Majority-Muslim Nations." Might provoke some analysis of the economic implications of "Islamophobia."
