Linetype connecting ends of dumbbell chart - feature request

[al-obrien]

Hello,

I was wondering if a feature for geom_dumbbell() that would allow the user to select the linetype used to connect the ends of each point has been considered. Or perhaps I am missing something in the documentation. I looked through past issues that may be related to this request but the closest I found was a thread asking for a parameter for arrows/direction.

Thank you!
