A tree diagram is a human-made visual construct for representing hierarchical relationships: entities or categories are displayed as nodes connected by directed edges in a top-down structure, where parent nodes contain child nodes that show subcategories or component parts. The layout uses spatial arrangement (vertical or horizontal) to encode hierarchy depth, and node shapes or colors often distinguish entity types. Persistence mechanism: standardized diagramming conventions documented in information design literature and implemented through drawing software and template systems.

Why it is in scope
A human-made visual construct that represents hierarchical relationships using nodes and directed edges arranged in a top-down structure, where each node displays a category or entity and its children show subcategories or components

A tree diagram is a specific kind of chart — a graphical representation of a hierarchical structure. A competent speaker would say 'a tree diagram is a chart.' Meets Law 9.

A radial tree IS a specific kind of tree diagram — it represents the same hierarchical structure as a tree diagram but with a radial (circular) layout instead of linear. A competent speaker would classify a radial tree as a type of tree diagram. Law 9 specific→general.

A sunburst diagram is a specific kind of tree diagram — it displays hierarchical data as concentric rings where each ring represents a level in the hierarchy. Files against nearest kind, not chart.

A dendrogram IS a specific kind of tree diagram: it visualizes hierarchical clustering results as branching nodes. A competent speaker would say 'a dendrogram is a kind of tree diagram.' Direction: specific→general. Nearest kind per Law 11e (tree diagram is more specific than plot).
