I think it depends what you think is easiest;

<TABLE CLASS="2dpie.My2DPieChart">, with
TABLE.2dpie.My2DPieChart : (etc, etc)


<TABLE CLASS="my2dpiechart">, with
TABLE.my2dpiechart : renderstyle.type = 2dpie

They both come out evens, really.

I'd only note that we're getting (once again) dangerously close to
introducing more presentation-orientated features into HTML by
specifying the chart type by saying that a table of CLASS="2dpie" is
a 2D-Pie chart. Like all the other "hints" regarding presentation,
I for one would prefer them to live in stylesheets with a more
content orientated value used for the CLASS attribute (say,
CLASS="meters.readings.june" or CLASS="building.floor.areas").
