Uncompromisingly Flexible Phylogenetic Trees in Javascript, powered by d3
This repository was created for use by CDC programs to collaborate on public health surveillance related projects in support of the CDC Surveillance Strategy. Github is not hosted by the CDC, but is used by CDC and its partners to share information and collaborate on software.
TidyTree is both a full-featured web application for users, along with the underlying library for developers.
It's designed to replicate much of the functionality of FigTree, though it's by no means a perfect replacement. It does, however, run entirely in-browser.
First import the library:
<scriptsrc="https://d3js.org/d3.v5.min.js"></script><scriptsrc="https://unpkg.com/tidytree@0.5.0/dist/tidytree.min.js"></script>(It requires d3!)
Then stick this in an HTML script tag:
letnewick="(A:0.1,B:0.2,(C:0.3,D:0.4):0.5);";lettree=newTidyTree(newick,{parent: "body"});And Voila! Your body will be populated by a phylogenetic tree.
tidytree is based on this gist (See in action), which "mostly just duplicates the cannonical[sic] d3.tree and d3.cluster bl.ocks by Mike Bostock."
MicrobeTrace needed a Phylogenetic Tree renderer that enabled rerooting and distance scaling. Additionally, there were a bunch of nice-to-haves, like Unrooted and Circular views, Zooming, Colorable and Selectable nodes... You get the idea.
As for the viewer, well, we needed a platform to rapidly prototype features for the library. The product of that is a single-page web application that leverages literally all of the features of the library. If you're a dork like me, you can see this in the coding of the index.html file. Notice how all of the select widgets are programmatically populated--that's so we could implement new features (e.g. layouts) without having to update the Demo HTML. After that, all we had to do was keep the UI clean.
