An SVG Bar chart showing the Dropbox userbase

This is a Bar chart that depicts the growing userbase of the Dropbox online service. It's customised using the xaxisScaleUnitsPost option (to add units to the Y axis), a large hmargin setting, the background grid has had the vertical lines disabled and the title is off-center.

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src=""></script>
Put this where you want the chart to show up:
<div style="width: 750px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
    new RGraph.SVG.Bar({
        id: 'chart-container',
        data: [100,300,400,500],
        options: {
            title: 'Dropbox userbase',
            hmargin: 50,
            colors: ['#DE2E2D'],
            backgroundGridLinewidth: 2,
            backgroundGridColor: 'gray',
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            yaxisScaleUnitsPost: ' million',
            marginTop: 50,
            marginLeft: 100,
            titleX: 100,
            titleY: 30,
            titleHalign: 'left',
            titleBold: true,
            titleItalic: true,
            yaxis: false,
            xaxis: false,
            xaxisTextColor: 'gray',
            yaxisTextColor: 'gray',
            xaxisLabels: ['November 2012','May 2014','June 2015','March 2016'],
            textSize: 9
