piegraphs. @Index { pie graphs }
pie. @Index { @Code "@Pie" symbol }
symbol.  For example,
@ID @OneRow -1px @Break @Code @Verbatim {
@Pie
{
    @Slice
        weight { 20 }
        label { Admin (20%) }
    @Slice
        weight { 40 }
        paint { green }
        label { Research (40%) }
    @Slice
        weight { 40 }
        paint { lightred }
        label { Teaching (40%) }
}
}
produces the pie graph
@CD @Pie
{
    @Slice
        weight { 20 }
        label { Admin (20%) }
    @Slice
        weight { 40 }
        paint { green }
        label { Research (40%) }
    @Slice
        weight { 40 }
        paint { lightred }
        label { Teaching (40%) }
}
This example shows off most of what @Code "@Pie" can do.
# there are many options, but for the most part they offer
# detailed adjustments, not additional features.
