Each strip is that field’s whole ranked pool, with the notch where Institut Fourier sits in it, in the colour of the band that rank falls in. The track under the rate is the rate itself: it carries no world mark, because the world rate differs by field (from about 6% to 21% in this record).

What does Institut Fourier specialise in?

Where its research is concentrated relative to its size: Geometry and Topology takes 125.3× the share of its output that it takes of world research.
