I idly thought up this visualization of the Sieve of Eratosthenes. The usual 2D grid makes sense when you have limited space on paper. But if you have a touchscreen with pan and pinch zoom it seems better to spread out the numbers in a single line. @dpiponi @mjd @ColinTheMathmo or others, do you happen to know a citation for something like this? Also please share any other visualizations. A web search found this other one: https://www.etsy.com/listing/1514771584/prime-numbers-sieve-of-eratosthenes
