Grasshopper - Interpolate curve through points

[Julien_01 (Julien)]

Hi everyone,

I’m having a hard time to interpolate a curve through points so I could achieve a sort of a “mandala” pattern tree as shown in the image that I’ve modelized by hand in Rhino.

Could someone help me on why the interpolated curve forms a loop?

Thanks,

A quick fix, but it would be better if you did this correctly from the start:
