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.

Does anyone have any ideas? It draws the lines trying to avoid overlapping other lines in a very pleasing manner. Doing this is probably outside the scope of the Shape Tools plugin, but I just wanted to ask to see if there is a relatively easy algorithmic way of drawing these types of lines between two points.
