        Chart Features
        --------------

        This chart is created by adding two pies and some graphics on the same canvas. It may seem a bit
        fiddly to do all this to lay out a single chart, but if you consider the fact that this single
        python module can now be used to generate batches of thousands of charts, with different
        data for each passed in dynamically, you can appreciate that a bit of work up front to get an
        exact template can save massively.
