SelfLoopStyle

SelfLoopStyle
is an option for GraphPlot and related functions which specifies how to draw self-loops that connect a vertex to itself.

	Automatic	draw self-loops for graphs given by explicit rules
	All	always draw self-loops
	None	never draw self-loops
	d	draw self-loops as loops of radius d

With SelfLoopStyle->Automatic, self-loops are not drawn for graphs specified by adjacency matrices.

SelfLoopStyle->1 makes self-loops have diameters roughly equal to the average edge length in GraphPlot graphs.
