Hi,
  Just draw a sphere if you like:
draw delete all
draw color blue
draw sphere { 0 0 0 } radius 1.0 resolution 16

If you want to vary the radius of arbitrary atoms in VMD, you
can use an atom selection to change them like this (ridiculously
large example in this case):
  set sel [atomselect top "index 1"]
  $sel set radius 10.0
