Rotating cylinder gradient, need help

Hi! I’m new to grasshopper and am wanting to model this pavilion. I am wanting to create a tube system that starts horizontally on the base (as you can see in the rhino file photos) and slowly twists up to be vertical. I’ve attempted it just in rhino to give an idea but would love it if it could be parametrically done.Scanned Documents.pdf (401.6 KB)
