react-tree-graph

A simple react component which renders data as a tree using svg.

Installing

npm install react-tree-graph --save

Usage

import Tree from 'react-tree-graph';

let data = {
	name: 'Parent',
	children: [{
		name: 'Child One'
	}, {
		name: 'Child Two'
	}]
};

<Tree
	data={data}
	height={400}
	width={400}/>);

If you are using webpack, and have css-loader, you can include some default styles with:

import 'react-tree-graph/dist/style.css'

Alternatively, both the JavaScript and CSS can be included directly from the dist folder with script tags.
