Vectrosity line with arrow

But as it is intended to be a directed graph, it would be visibly more intuitive if the edges had an arrow to indicate direction.

Is there any way to draw arrows with Vectrosity or otherwise?

You could use some kind of arrow texture along with SetTextureScale, so the lines would look something like this:
