            Property Value
The default value is 
NaN. 
NaN indicates that the 
Spacing will determing size of ring. If 
Spacing is also 
NaN, the effective spacing will be 6. If 
Spacing is a number, the effective radius will be > Radius if and only if the spacing between elements would otherwise be less than spacing. The specified value for 
Radius will be ignored if 
Arrangement==
CircularArrangement.Packed. This property must always be positive or 
NaN.
