How the corpus scores
Each dot is a repo, colored by grade. Corpus medians divide the four quadrants - hover any dot to identify it, or hover a region for a summary. Distributions below show the same data sliced by band and popularity tier.
Quality vs popularity
Each dot is a repo, colored by grade. Hover a region to highlight it and see counts. Toggle the X axis between stars and contributors.
Score distribution
Repos per 10-point band, colored by grade
Score distribution by popularity
Box = P25-P75, line = median (colored by grade), whisker = P10-P90
GitHub stars · box = P25-P75, line = median, whisker = P10-P90
Scores climb steadily with popularity
Median score within each star tier. The grade mix hides this because most repos have few stars - but quality and reach rise together.
What top repos do that the rest don't
Hollow dot = D/F pass rate, filled dot = A/B pass rate. The gap is the real signal. Filtered to Shell. Based on 97 repos.
Pass rates side by side
