The number is the rank inside the country. The track on each row is the top-10% rate; the tick is the average of all institutions, 16.5% (why not 10%): teal above it, red below. The ranking is the quality score, which compares the rate with what each institution's own topics predict and adds a small reward for size, so the rates do not fall in order.
