the easiest way to do this is with a path string:
var s = 10 //grid size
var p0 = [10, 15] //start point
var p1 = [20, 25] //end point
var connectionpath = svg.append('path')
.attr('d', [
'm', p0[0]*s, p0[1]*s, //put pen at start point
'h', p1[0]*s, //move pen horizontally
'v', p1[1]*s //move pen vertically
].join(' '))
.attr('fill', 'none')
.attr('stroke', '#000')
to adjust when the rectangles are dragged, update the d
attribute each time one of the rectangles is dragged.
