$(function () {
var chart;
$(document).ready(function() {
    chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',
            type: 'bar'
        },
        title: {
            text: 'Historic World Population by Region'
        },
        subtitle: {
            text: 'Source: Wikipedia.org'
        },
        xAxis: {
            categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
            title: {
                text: null
            }
        },
