How can I draw multiple parallel edges in neato?

When the splines attribute is false, which is the default, multiedges are drawn as a spindle of simply curved edges. There is no attempt to avoid intervening nodes.

When splines=true or polyline, multiedges are drawn as roughly parallel splines or polylines. This relies on there being no node overlaps.

An additional trick which is sometimes sufficient is to specify multiple colors for the edge using a color list. This will a produce set of tightly parallel splines, each in its specified color. Read about the color attribute for more information.
