We were inspired by Hans Rosling and created this viz before the SEE 12 meeting in Athens next week! Each bubble represents a country. We can observe their progress in RPKI and IPv6 from 2016 to now.
The sizes of the bubbles are proportional to the number of active LIRs from each country. The horizontal axis shows the ROA coverage of the IPv4 space and the vertical axis shows the percentage of IPv6 capable networks.
