lwPhylo

A lightweight, low level javascript library to plot phylogenies from a Newick file. It uses no dependencies on any other package, but is designed to be given to the D3 library for visualisation.

Newick trees can be parsed using the readTree() function. This object can then be wrapped in three main functions; rectangleLayout() to produce a "regular" phylogenetic tree, radialLayout() to produce a circular phylogeny, and unrooted() to produce an unrooted tree via the equal angle layout algorithm.

A quick tutorial is now available to see on Observable: https://observablehq.com/@euphrasiologist/lwphylo-tutorial \
It goes over the three tree layout functions, and hopefully is all quite straightforward.

Stay tuned for examples in the browser.

Original implementation of tree layout schemes are found here: https://github.com/ArtPoon/ggfree.
