Can a phylogram or other branch-length-respecting tree be rendered in the visualization API? A phylogram is a type of tree representation. They could be seen as types of "organizational chart", but the Google "organizational chart" API doesn't seem to be capable of rendering them. These trees differ from the Google "organizational chart" in the following ways:
1: The interior nodes are almost never explicitly represented or even named. They can simply be points of connection with no explicit identity beyond that. 2: The LENGTHS of the edges (branches) matter. It is not only important that "X", "Q", and "Z" descend from "Y", but how far back They all split from (or continued) "Y". 3: Unrooted trees have a more radial and irregular appearance (as well as no external root), particularly to highlight comparisons of distances instead of the hierarchical structure. Can this be done in the Google API but I've merely missed it? I could theoretically fake this with a lot of calculation and a scatterchart, but I'd like to render it "native". I suppose it's far too much to hope that, if Google API can handle this concept, it can do it from the most commonly used, WORLDWIDE, method of representing a phylogram, the "Newick" format. Example of Newick format tree: (((((CBS:0.132941702,Sean_Hannity:0.132941702):0.1550955605,ABC:0.2880372625):0.311266502,((NBC:0.211372502,Maddow:0.211372502):0.1850476855,Fox:0.3964201875):0.202883577):0.393478953,CNN:0.9927827175):1.209381255,((Glenn_Beck:0.5661413985,Rush_Limbaugh:0.5661413985):0.2989921065,Bloggers:0.865133505):1.337030468); I have attached an image of how this would render as an "unrooted tree". -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
