I am interested in doing this too.    I have created Origin-Destination Links but my data is very local.   About 40 miles maximum from origin to destination and much less on average.    I would like to create circular arcs from the origin to the destination like the graphic in this thread but haven't found much that will do that.  I have some arcpy samples but they don't produce the effect desired.   Thank you for any further options.

This is what is called a Spider Diagram.  You can generate these using the Generate Origin-Destination Links  geoprocessing tool.  You'll need to use the Geodetic option for the Line Type parameter as this will produce the 'great circle' lines shown in your graphic.
