Is there any way to place a rectangle so that its west edge is at a specific point, rather than its center?
example: I would like to take the rectangle containing ASDF and move it so its west edge lines up with the center of the gray circle (node R9).

/* Create nodes numbered nxy with "xy" from istart to istop,
* starting at the origin, with horizontal separation dx
*/
let nodename(i) = {
let si = str(i)
label("n" + ("00"+si).slice(-2))
}
for i in range(istart, istop+1) {
node((rel: (i*dx, 0cm), to: origin), shape: circle,
name: nodename(i),
radius: radius, ..nodefmt)
}
edge(nodename(istart), nodename(istop), stroke:linestroke)
}
