Commenters find the diagrams awesome and nice

It's awesome. That's really nice. One thing, when I pick a number with an annoyingly large prime factor (e.g. 1655=5*331), it seems to drop the large factor. At some point that…

Large prime factors render as tiny dots that look like circles, hard to read

mcnamaratw on HNOhhhh, so when I do 1655 I'm not just getting a pentagon, I'm getting five circles, each made out of 311 little tiny dots? (Or however many dots it is :P)

Large inputs make the UI unresponsive due to slow factorization or drawing
From 2 comments
Slightly offtopic: if I type "123456" the UI becomes unresponsive (cannot type backspace for instance). It may be that the language Purescript is "lazy", but somehow this does…
amelius on HNI added a hard limit of 10,000 (in the input field and the code), because the prime factorization will be too slow otherwise. Maybe your browser takes a long time to draw the…

Colors differ for primes 13 and 19 without clear reason

Why do 13 and 19 look so much different?

Better scaling so large prime factors are visible
From 1 comment
Huge prime factors are indeed a problem (in the sense that the simply look like circles). I think I can work a little bit on the scaling of the diagrams (there is still some free…
