I did this rather fast. Coulda consolidated some categories. The Maroonish colored category (lowest) is the widest disparity among the figures by a large margin - and has the most countries by far.. Israel leads that category and then it drops rather fast. While the other categories besides China are not far apart at all.
China leads Japan (in category by itself but coulda just consolidated them in with the dark blues) by a wide margin.
Poland, in the 3rd category (dark blue), is 3rd overall, which surprised me a bit.
