Research trend share of papers by all institutions in South America, per year

Each point is this institution's share of the papers credited to all institutions in South 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.
