Each strip is that field’s whole ranked pool, with the notch where National Zoological Park 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 National Zoological Park specialise in?

Where its research is concentrated relative to its size: Ecology takes 25.3× the share of its output that it takes of world research.
