Correlation between country governance regimes and the reputation of their Internet (IP) address allocations

[While getting our feet wet with D3 (what a wonderful tool!), we finally tried this analysis tidbit that's been on our list for a while.]

We recently analyzed the reputation of a country's Internet (IPv4) addresses by examining the number of blacklisted IPv4 addresses that geolocate to a given country. We compared this indicator with two qualitative measures of each country's governance. We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses.
