Need to adjust this code to be encapsulated. Linestyle is not being called correctly.

// // // centerX-- X origin of the spiral. // centerY-- Y origin of the spiral. // radius--- Distance from origin to outer arm. // sides---- Number of points or sides along the spiral's arm. // coils---- Number of coils or full rotations.
