Sieve of Eratosthenes

CSS

A square grid of integers is struck out multiple by multiple, the twos then the threes then the fives, until only the primes are left standing.

The Free licence asks for one visible credit per page: Animation by Pulsar, linked to Pulsar. The credit line is that link, ready to paste. The snippet itself carries attribution in a comment and in the SVG’s metadata, and never links anywhere on click. Licence
