countries ranked worldwide in Electronic, Optical and Magnetic Materials (47). rank on the composite score within the stated pool. The score track runs 0 to 100; the rate track carries no world mark, because the world rate differs by field.

How spread out this pool is

Every row above on one axis — one tick each, right is a higher score. A field where the top few are far clear of everyone and one that runs down evenly look identical as a table.
