    Description:
    The family tree represents the family pedigree in order to introduce the patient as part of his family, and supply information about other family members that are affected with the CF disease. The family tree, together with the additional data about the expanded family, gives a complete picture of the individuals who are sick in that family. The information helps, later on, to understand the way the faulty CF gene is inherited. The main idea in this feature is passing a lot of data without overwhelming the viewer.
    The Rationale Behind the Feature (Specific Design Principle):
    Showing a large amount of information in a way that does not overwhelm the student: On a simple diagram of a family tree, additional level of information on each of the family members can be retrieved by stepping with the mouse over that member. In general, any type of diagram that displays symbolically the relations between members of a given group (in this case - the relations of the people in the family) can be used.
    Context of Use:
    This feature is part of a WISE learning environment that teaches genetics through the story of Eric - a child with CF. It is used as a way to "interview" each of the family members and learn who is affected with CF.
    In general it can be used whenever there is a group of members which relations can be displayed using a specific type of diagram, and for each member there is some additional relevant information.
    Examples:
    - Family in a family tree, when each family member has a story
    - Organization in an org chart, with each member has his own CV
    - Social status as was found according to a psychometric test, with the hobbies of each of the members
