Represent the total mask usage data (for all counties) in a form of a pie chart

• Represent the total mask usage data (for all counties) in a form of a pie chart and a frequency plot.

My pie chart is not running, any idea why?

X = [92 85 84 83 83 83 77 77 71 63 59 57 54 35 19 10 9 4 2 2 2 ];
explode = {};
labels = {'Philippines', 'Mexico', 'Spain', 'Hong Kong', 'Italy', 'Thailand', 'Japan', 'Malaysia', 'Vietnam', 'Germany', 'U.S.', 'Taiwan', 'France', 'Canada', 'U.K.', 'Australia', 'Netherlands', 'Norway', 'Denmark', 'Finland', 'Sweden'};
pie(X,explode,labels)

explode=[];

to not use the parameter; the empty cell array doesn't work, the empty double does; a logical array is expected.
