Re: Border width for regions on a map/chart

Thanks for the reminder. It took me to process the difference between fig 6
and 7. The second row of fig 6 passes, and the first row of fig 7 doesn't
is because 6's border gets a hair thicker when the star gets selected. The
pie chart was insightful, and should be able to give me footing I need.
