I'm trying to draw curved lines between nearby locations in leaflet.

All the responses to similar questions on SO suggest using gcIntermediate() from the geosphere package, however that does not work for nearby locations as the curvature is so slight that it will still look like a straight line.

So starting with two pairs of lat/lon coordinates (origin x/y, end x/y), is there any way to accomplish this?
