A) An example of a cladogram representation: a branching diagram assumed to be an estimate of a phylogeny. B) An example of a phylogram. A phylogram is different from a cladogram with respect to the fact that the branch lengths are proportional to the amount of inferred evolutionary change. C) An example of an unrooted cladogram. An unrooted tree can be rooted on any of its branches, and so there are many rooted trees that can be derived from a single unrooted tree. D) An example of a circular cladogram. These kinds of layout types place the nodes in concentric rings around the center. E) An example of a slanted cladogram. The sloped version of the rectangular layout remains equally informative and efficient. F) An example of a hyperbolic tree. G) 3D Trees by 3DPE (3D Phylogeny Explorer) tool.
