    A bullet chart is a variation of a bar graph
    used to indicate the value of a single variable
    in relation to a set of qualitative ranges. It is
    inspired by a dashboard gauge or thermometer chart.

    Python example:

        from nvd3.bulletChart import bulletChart
        chart = bulletChart.bulletChart(name=chart_name, height=100, width=500)
        title = 'Revenue',
        subtitle = 'US$, in thousands'
        ranges = [150, 225, 300]
        measures = [220, 270]
        markers = [250]
        chart.add_serie(
            title=title,
            subtitle=subtitle,
            ranges=ranges,
            measures=measures,
            markers=markers)
        chart.buildhtml()
        print(chart.content)
