The most common family tree structures are:
- A horizontal tree: This is the most common type of family tree. It consists of a horizontal bar (or a few lines) representing the family members and their relationships.
- A vertical tree: This tree is typically composed of a vertical bar or a series of vertical lines.
- A nested tree: This tree has a nested structure, where each member of the family is a root of the parent family.
- A tree with a "node" or "child" node: This tree has a node that represents a specific member of the family. The node has a name and a parent.
These are the most common types of family tree structures.
