The arrow line renderer is close to what I want but only does a simplistic curve. In the example, notice how lines emerge at different bearings depending on the number of lines coming to or from each node. Also the curves are circular in nature but not a circular arc. They are more of a spline. I

I don't know but am guessing, but aren't those lines not just *any* circular arcs, but the actual great-circle paths (the shortest line between two points on the surface of a globe) plotted onto that map projection? Some of them towards the edges aren't circular. On 26/09/2018 21:34, C
