i find that hard to estimate. a day or less for some. i ported the webby thing to vanilla js in a couple of days. might have been slightly faster if i used p5js. but others might take weeks or even months. depending on how much experience you have spent working with graph structures for example. as with a lot of programming it's not always that hard if you know precisely what you are making (if you have done it before.) related: someone who has not done a lot of generative art might be surprised by how complicated some things are and others aren't. not always obvious from the visual result. edit: i guess maybe you just meant how long it would take me. but the answer is sort of the same.
