Country × Country censorship correlation
Pearson correlation across 365-day daily incident vectors for the top 50 most-censored countries (by Atlas Score v2). Pairs that fire together — regional shutdown waves, regime- similar blocking patterns — light up here the day they emerge.
Computed at request time over 1,291 incidents. 1-hour ISR. Source ranking →

Method & honest caveats
- Window: 365 days ending today (2026-06-08). Vectors are daily incident counts per country.
- Countries: top 50 by Atlas Score v2 (50% structural baseline + 50% recent activity).
- Statistic: Pearson correlation. No significance test surfaced here — small N-days mean even high r can be noise. Treat this as an exploratory surface, not a confirmatory one.
- The interpretation column above uses a hard-coded regional peer map. A "regional cluster" tag is a hint, not a causal claim.
- Diagonal is masked. Negative r is rendered blue; positive red; near-zero gray.
