Code page with highcharts graph displaying blank

I am dipping my toe into using Highcharts graphs and have hit a wall. I should first say that I am a novice, so don't assume much of anything regarding my skill level!

I created a code page (test.html) with a basic sample bar chart that doesn't pull from QuickBase - the data is in the code. I got something similar working using charts.js but when I tried Highcharts it just displays a blank page. I would be grateful if someone could A) explain what I am doing wrong and/or B) point me to a tutorial on using highcharts in QuickBase.

Thanks!

The code is: 

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>

<div id="container" style="width:100%; height:400px;"></div>

<script type='text/javascript'>
Highcharts.chart('container', {
        chart: {
            type: 'bar'
        },
        title: {
            text: 'Fruit Consumption'
        },
        xAxis: {
            categories: ['Apples', 'Bananas', 'Oranges']
        },
        yAxis: {
            title: {
                text: 'Fruit eaten'
            }
        },
        series: [{
            name: 'Jane',
            data: [1, 0, 4]
        }, {
            name: 'John',
            data: [5, 7, 3]
        }]
    });
})
</script>
