The underlying JavaScript code

<input type="text" id="input" value="sin(x)*x">
<input type="button" value="plot" onClick="plotter()">
<input type="button" value="clear all" onClick="clearAll()">
var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,8,8,-5], axis:true});

function plotter() {
  var t = JXG.GeonextParser.geonext2JS(document.getElementById('input').value);
  var f = new Function('x','var y = '+t+'; return y;');
function clearAll(board) {
    board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,8,8,-5], axis:true});
