A radial tree is a hierarchical data visualization in which nodes are arranged in concentric rings or circles around a central root node, with edges drawn as lines or curves radiating outward from the center. Each ring represents a depth level in the hierarchy, and sibling nodes are distributed angularly around their parent. The parameters that delimit a radial tree are: (1) the input is a rooted hierarchical structure, (2) nodes are positioned by depth (radius from center) and by relative sibling ordering (angle), and (3) edge routing follows the radial layout without crossing where the hierarchy permits. Persistence is maintained through diagramming software, layout-algorithm implementations, and hierarchical data formats (JSON trees, XML) that encode parent–child relationships.

Definition
Why it is in scope
A human-made visual construct for representing hierarchical relationships using nodes and directed edges arranged radially from a root node at the center, with branches extending outward in concentric layers

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 radial tree is a specific kind of graph: nodes are arranged in concentric circles radiating from a root, with edges drawn radially. It is a concrete instance of the general graph concept, where the radial layout is a structural convention, not a different ontological category.
