Older demo added to the download archive

I realised recently that a demo that I showed a screenshot of on this blog, albeit some time ago, wasn't in the download archive. So I've remedied this and the new demo is called demos/bar-grouped-purple.html (it'll be in the next release). Here's an example of it in case you're curious. The source code of the chart is as follows:

<script>
    labels = [
        '0 to 4','5 to 9','10 to 14','15 to 19','20 to 24','25 to 29','30 to 34',
        '35 to 39','40 to 44','45 to 49','50 to 54','55 to 59','60 to 64',
        '65 to 69','70 to 74','75 to 79','80 to 84','85 to 89','90+'
    ];
    
    myData = [
        [750,650],[850,800],[900,850],[1500,2800],[4000,7000],
        [6300,11500],[7000,11200],[6800,9800],[6800,9500],
        [7500,11200],[8500,12300],[8500,11000],[7500,7800],
        [6050,4500],[6900,5000],[8000,6400],[9000,8900],
        [8000,10000],[5900,11850]
    ];

    new RGraph.Bar({
        id: 'cvs',
        data: myData,
        options: {
            title: 'A demo of the new style of tooltips',
            titleSize: 16,
            titleBold: true,
            tooltips: '%{global:labels[%{group}]} %{key}',
            tooltipsFormattedKeyColorsCss: {
                border: '1px solid #ccc'
            },
            tooltipsFormattedKeyLabels: ['Male','Female'],
            tooltipsCss:{
                textAlign: 'left'
            },
            tooltipsOffsety: -5,
            colors: ['#5C1955','#62A3B3'],
            marginBottom: 75,
            marginLeft: 75,
            xaxis: false,
            yaxis: false,
            xaxisLabels: labels,
            xaxisLabelsAngle: 45,
            xaxisLabelsOffsety: 5,
            yaxisScaleMax: 15000,
            backgroundGridVlines: false
        }
    }).draw();
</script>
