Looking at a basket of countries total GDP for comparing size of economy. Makes it easy to select your own groupings of countries for comparison. A country's GDP is the total of consumer spending (C) plus business investment (I) and government spending (G), plus net exports, which is total exports minus total imports (X – M). Alliances visualized was the original idea but wasn't quite sure for a lot of other countries where they stand so it is what it is; feel free to improve.
