MultiedgeStyle

MultiedgeStyle
is an option for GraphPlot and related functions that specifies how to draw multiple edges.

	Automatic	draw multiple edges for graphs given by explicit rules
	All	always draw multiple edges
	None	never draw multiple edges
		spread multiple edges by scaled distance

With MultiedgeStyle->Automatic, multiple edges are not drawn for graphs specified by adjacency matrices.
