Many fundamental data structures in mathematics and science can be visualized as trees. Tree objects are automatically displayed in a notebook as a plot of a tree graph, allowing hierarchical structures to be easily inspected. The Wolfram Language provides in-depth support for every aspect of styling, labeling and rendering trees. Options specified by a tree can affect its root node and parent edge, as well as those of any subtrees at positions matching a pattern, including inheriting and overriding settings.
