PhyD3

A phylogenetic tree viewer.

Installation

Using npm:

npm install @vibbioinfocore/phyd3

Using yarn:

yarn add @vibbioinfocore/phyd3

Usage

import { makeCompatTable, phyloxml } from "@vibbioinfocore/phyd3-parser-compat";
import { build } from "@vibbioinfocore/phyd3";

const xml = "<phyloxml><phylogeny rooted='true'><clade><name>A</name></clade></phylogeny></phyloxml>";

const parser = new DOMParser();
const doc = parser.parseFromString(xml, "text/xml");
const svg = build(makeCompatTable(phyloxml.parse(doc)));

// insert svg.node() somewhere in your document

Options

Parsing

PhyD3 does not perform any parsing. You can use a compatible parser such as Phylio or phyd3-compat-parser or use any another parser. If you use another parser you will have to transform the result into a structure that PhyD3 expects. This is described below. As an example, see phyd3-compat-parser::makeCompatTable().

{
  "metadata": Array<Metadata>, // A metadata structure for each phylogeny (there may only be one)
  "nodes": Array<Node>,        // All nodes in all phylogenies
  "edges": Array<Edge>         // All edges between nodes (this will form a disconnected graph)
}

This is what a metadata structure looks like:

{
  name: string | undefined,        // The name of this phylogeny
  description: string | undefined, // A description of this phylogeny
  parent: number,                  // The unique numeric identifier of the root node for this phylogeny
  rooted: boolean                  // Whether this phylogeny is rooted of not
}

An edge looks like this:

{
  source: number, // The unique identifier of the starting node for this edge
  sink: number,   // The unique numeric identifier of the ending node for this edge
  length: number  // The length of the edge
}

And finally, this is a node.

{
  name: string,
  event: "Clade" | "Taxa" | "Hybrid" | "LateralGeneTransfer" | "Recombination",
  ref: number, // The unique identifier for this node
  attributes: Map<string, Attribute> // A set of attributes
}

Attributes may either be scalar values, lists, or sub-mappings:

type Attribute
  = {tag: "numeric", value: number}
  | {tag: "text",    value: string}
  | {tag: "bool",    value: boolean}
  | {tag: "list",    value: Array<Attribute>}
  | {tag: "mapping", value: Map<string, Attribute>}
