I don't know whether it's normal or not; it might have happened that
there are a few nodes that are connected only very loosely to the rest
of the network and these were placed very far from the Y axis,
effectively squeezing the rest of the network into the area close to the
Y axis. I'm not sure. If I were you, I would try the original DrL
implementation and read its documentation as well (I think it's in the
downloadable source code package):
