Hi, Perl monks

I got this code from below URL

https://metacpan.org/pod/release/JMCNAMARA/Excel-Writer-XLSX-0.94/lib/Excel/Writer/XLSX/Chart/Doughnut.pm 


#!/usr/bin/perl
 
use strict;
use warnings;
use Excel::Writer::XLSX;
 
my $workbook  = Excel::Writer::XLSX->new( 'chart_doughnut.xlsx' );
my $worksheet = $workbook->add_worksheet();
my $bold      = $workbook->add_format( bold => 1 );
 
# Add the worksheet data that the charts will refer to.
my $headings = [ 'Category', 'Values' ];
my $data = [
    [ 'Glazed', 'Chocolate', 'Cream' ],
    [ 50,       35,          15      ],
];
 
$worksheet->write( 'A1', $headings, $bold );
$worksheet->write( 'A2', $data );
 
# Create a new chart object. In this case an embedded chart.
my $chart = $workbook->add_chart( type => 'doughnut', embedded => 1 );
 
# Configure the series. Note the use of the array ref to define ranges
+:
# [ $sheetname, $row_start, $row_end, $col_start, $col_end ].
$chart->add_series(
    name       => 'Doughnut sales data',
    categories => [ 'Sheet1', 1, 3, 0, 0 ],
    values     => [ 'Sheet1', 1, 3, 1, 1 ],
);
 
# Add a title.
$chart->set_title( name => 'Popular Doughnut Types' );
 
# Set an Excel chart style. Colors with white outline and shadow.
$chart->set_style( 10 );
 
# Insert the chart into the worksheet (with an offset).
$worksheet->insert_chart( 'C2', $chart, 25, 10 );
