Research trend share of papers by government research bodies in North America, per year

Each point is this institution's share of the papers credited to government research bodies in North America that year, with credit split across co-authoring institutions. A share, not a count, because our collection grows unevenly by year. Hover a point for the figures. The hollow point is the year in progress.
