I'm making a wine rack:

and I was wondering how to lay out that sine curve on the piece
of wood to cut it.

For future reference, if you want a real sine curve, and not an
approximation [within the bounds of the tools and shaky hands]
use a math program like Graphmatica, then copy/paste into a word
processor or image editor for printing to the scale you
want/need.

Or, any basic trig text shows how to draw it from the unit
circle.

That's what I was going to suggest. It's easy, and you can easily
scale the sine curve as large or small as you like by choosing an
appropriately-sized circle. Since all that's required is a compass
and straightedge you don't even have to leave the shop.
