Example use

import createTree from '@mkoliba/phylogeny-tree/createTree';
import interactionsPlugin from '@mkoliba/phylogeny-tree-plugin-interactions/index';
import '@mkoliba/phylogeny-tree-plugin-interactions/styles.css';
import contextMenu from '@mkoliba/phylogeny-tree-plugin-context-menu/index';
import '@mkoliba/phylogeny-tree-plugin-context-menu/styles.css';

const newick =

const canvas = document.querySelector('#canvas'),
const options = {
    source: newick,
    renderInternalLabels: true,
    rotatedIds: [
      '6',
    ],
    styles: {
      Mouse: { shape: 'square', fillStyle: 'red' },
      Human: { shape: 'triangle', fillStyle: 'green' },
      Gibbon: { shape: 'star', fillStyle: 'blue' },
      Bovine: { shape: 'hexagon', fillStyle: 'orange' },
      Chimp: { shape: 'hexastar', fillStyle: 'grey' },
      Orangutan: { shape: 'octastar', fillStyle: 'indigo' },
    }
  }
const plugins = [
    contextMenu,
    interactionsPlugin
  ]

const tree = createTree(canvas, options, plugins)

In React project use [react-phylogeny-treettps://github.com/mkoliba/react-pppphylogeny-treeh wrap Phylocanvas3 in component or hook.

Properties of options object overide default options properties ({ ...defaultOptions, ...options }) and resulting object is set as initial state of the tree.

Some of available options:

• source: newick tree string, or object {type: 'biojs', data} where data key contains to biojs-io-newick tree object received from parser.parse_newick.

For others check default options and examples in dev folder.

((tree: Tree, decorate: (fnName: string, fn: unknown) => void) => void)[];

Available plugins:

• @mkoliba/phylogeny-tree-plugin-context-menu: adds context menu
• @mkoliba/phylogeny-tree-plugin-interactions: adds interaction features such as zoom, highlight, selection, view of subtree
• @mkoliba/phylogeny-tree-plugin-scalebar: adds a scalebar to bottom left corner of canvas for length reference.
• @mkoliba/phylogeny-tree-plugin-annotations: adds annotations above leaves
• @mkoliba/phylogeny-tree-plugin-metadata: adds additional metadata lables and markers next to leaves
