How to bend a sinusoid into a circle in Sverchok? What's the best way in Sverchok to create a circular sinusoid, like I drew here with the grease pencil?



I can imagine one one:

1) displace the circle vertices along their normal; or
2) generate a sin curve and wrap it around an origin point

Or maybe there is a third way? Is one of these methods preferable, or more generically useful, from a Sverchok perspective? What would the node setup be?
use simple translate node and x+1 hack to fit vertices
