What does "connect" mean to you? Do you want every single endpoint connected to every other endpoint with a line drawn in the overlay? Or what? Maybe you want edgelinking http://www.csse.uwa.edu.au/~pk/Research/MatlabFns/#edgelink?

Can you mark it as Accepted? You can still come back with questions though.
