Hey Fernando, The graph/network support in PyQtGraph isn't very extensive, and this isn't something that comes built in. As a first pass on implementing this, I would build a bunch of CurveArrows at the mid-points of all the edges ( and make sure to set `pxMode` to false or it'll be a messy zoom experience ). Put in a new kwarg ( "showEdgeDirection"? or perhaps more flexibility with an "edgeSymbols" optional list ) on `GraphItem.setData`, make sure the performance isn't egregious ( mostly just finding all those angles and midpoints efficiently ), and that's nearly everything you'll need for a PR!
