    we will be updating various class names to use dashes, instead of
    underscore or camelcasing, to match with Bootstrap's convention.
    All instances of HTML class 'd3_pie_chart_usage' to 'pie-chart-usage'.
    All instances of HTML class 'd3_pie_chart_distribution' to
    'pie-chart-distribution'.
