Here shows the Genogram treemap of Alex's family. A genogram is a visual mapping tool that illustrates a person's family tree, relationships, and history. It is more than the traditional family tree giving insights into the medical history and behaviors of at least three generations of the family. A genogram is created with simple symbols representing the gender, with various lines to illustrate family relationships. Some genogram users also put circles around members who live in the same living spaces. Genograms can be prepared by using a complex word processor, or a computer drawing program.
