\n\n# Radial tidy tree\n\nD3’s [tree layout](https://d3js.org/d3-hierarchy/tree) implements the [Reingold–Tilford “tidy” algorithm](http://reingold.co/tidier-drawings.pdf) for constructing hierarchical node-link diagrams, improved to run in linear time by [Buchheim *et al.*](http://dirk.jivas.de/papers/buchheim02improving.pdf) Tidy trees are typically more compact than [cluster dendrograms](/@d3/radial-cluster/2?intent=fork), which place all leaves at the same level.
