Luiza's Geongram treemap is shown below. A genogram is a pictorial representation of a person's family tree, relationships, and background. It's more than just a typical family tree; it provides information on the family's medical history and behaviors for at least three generations. A genogram is made up of simple symbols that signify gender and different lines that depict familial links. Some genogram users also draw circles around family members who share living quarters. A complicated word processor or a computer graphics application can be used to create genograms.
