11. A system for placing spine groups within a display, comprising: a shape defined within a display; a unique placement module to place groups of cluster spines circumferentially around the defined shape; an overlap module to identify overlap between at least two of the spine groups; a rotation module to rotate one of the overlapping spine groups in one of a clockwise and anticlockwise direction away from the other overlapping spine group; a further overlap module to determine that overlap exists between the rotated spine group and at least one of the other overlapping spine group and another placed spine group; a translation module to move the rotated overlapping spine group in an outward direction away from the shape; and a processor to execute the modules.

A system according to claim 11 , wherein the rotation module sets a maximum and minimum angle for rotating the overlapping spine group in one of a clockwise and anticlockwise direction away from the other overlapping spine group and moves the rotated overlapping spine group in an outward direction away from the defined shape when one of the maximum or minimum angle is to be exceeded and the overlap exists between the rotated spine group and at least one of the other overlapping spine group and another placed spine group.
