Produce the detail pie chart.This graph uses the data set entitled CARS found in the SASHELP library. The DETAIL= option produces a inner pie overlay showing the percentage that each DRIVETRAIN contributes toward each type of vehicle. The DETAIL_PERCENT= option and the DETAIL_SLICE= option control the positioning of the detail slice labels. The DETAIL_VALUE= option turns off the display of the number of DRIVETRAINS for each detail slice. The DETAIL_THRESHOLD= option shows all detail slices that contribute more than two percent of the entire pie.
