Computer-implemented node spreader

A computer readable medium encoded with software instructions for enabling a method for displaying hierarchical data nodes on a display device, said method comprising the steps of:

• receiving first positions for locating a first node and a second node on the display device,
• wherein the first node and second node are separated from each other and are at least substantially equidistant from a predetermined center position on the display device;
• determining second positions for the first node and second node such that angular shift of the first node from its first position to its second position is different in magnitude than angular shift of the second node from its first position to its second position,
• wherein the angular shifts for the first node and second node are with respect to the center position;
• and
• displaying the first node and second node on the display device based upon the determined second positions for the first node and second node.
