RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including graphing. Try it out:
require('canvas');
var graphing = require("graphing");
var Graph = graphing.Graph;
var graph = new Graph('red',400,400,-10,10);
graph.graphLines();
graph.addFunction('x^2');
graph.addFunction('x');
graph.drawFunction(0,'deeppink');
graph.drawFunction(1,'dodgerblue');
graph.getGraph();
