Patent ID: 8229967

Claim:
A system comprising: an output device; a processor operably coupled to the output device; and a computer-readable medium operably coupled to the processor, the computer-readable medium having instructions stored thereon that, when executed by the processor, cause the system to identify a root individual in a genealogical dataset; identify a first parent and a second parent of the identified root individual from the genealogical dataset; identify a third parent and a fourth parent from the genealogical dataset, wherein the third parent and the fourth parent are parents of the identified first parent; control presentation of a pedigree visualization relative to the identified root individual by the output device, wherein the pedigree visualization includes a root indicator for the identified root individual, a first parent indicator for the identified first parent, a second parent indicator for the identified second parent, a third parent indicator for the identified third parent, and a fourth parent indicator for the identified fourth parent, and further wherein the first parent indicator is positioned along a first axis through the root indicator, the second parent indicator is positioned along the first axis through the root indicator in the opposite direction as the first parent indicator relative to the root indicator, the third parent indicator is positioned along a second axis through the first parent indicator, wherein the first axis is perpendicular to the second axis, and the fourth parent indicator is positioned along the second axis through the first parent indicator in the opposite direction as the third parent indicator relative to the first parent indicator.
