    Chart Features
    ==============

    This chart is closely related to the 'silly' line chart
    with markers. The key attributes that have changed are:

    - **chart.lines.symbol.kind** was changed from 'FilledCross' to 'Smiley'
    - **chart.lines.symbol.size** was changed from 5 to 15
    - **chart.lines.symbol.angle** was changed from 45 to 0 in order
    to prevent the smiley faces from being rotated
    - **legend.columnMaximum** was changed from 1 to 2, forcing the 
    legend into a single stacked column
    - **legend.y** was increased to push the legend up
    - **legend.x** was increased to move it to the right across the chart
