In -Tplain format, splines do not touch the nodes (arrowheads are missing).

Edges are specified as the main spline and, if necessary, arrowheads which actually abut the node. If the arrowheads are not given, drawing the edge spline will leave a gap between the edge and the node. This is a bug which has now solidified into a feature. A workaround is to set

  • edge [dir=none]

Since the edges have no arrowheads, the spline specification will go all the way to both nodes.
