    $\begingroup$ About 6 percent of men (many less women) are blindcolour. Please be nice for these disabled persons and don't use green and red spots in the same figure. $\endgroup$ Commented Mar 11, 2016 at 15:12

    $\begingroup$ What do the axes mean? And what are the blue dots? $\endgroup$ Commented Mar 12, 2016 at 23:33

    $\begingroup$ the plot shows for each integer n=1..10000 the number of sequences in OEIS in which n appears. The unexpected thing is the white strip in the points cloud, which shows there are numbers more "interesting" (above) than others (below). The blue dots are numbers which do not belong to the 3 "base" properties (primes, perfect powers, HCN) $\endgroup$ Commented Mar 14, 2016 at 6:22

    $\begingroup$ I made a similar plot back in 2006 by querying Google for each number and using the purported number of search results as a value. Sloane's gap appears here too, separating primes from ordinary numbers: imgur.com/a/edAhR $\endgroup$ Commented Feb 26, 2017 at 21:05

    $\begingroup$ So, basically, primes. $\endgroup$ Commented Mar 20, 2021 at 17:21
