### Making Graphs with Perl and Chart::Clicker

The Graph

The Code
`#!/usr/bin/perluse 5.010 ;use strict ;use warnings ;use Chart::Clicker;use Chart::Clicker::Data::Series;use Chart::Clicker::Data::DataSet;my \$pi = 3.14159265358979;sub deg_to_rad { (\$_[0]/180) * \$pi }sub rad_to_deg { (\$_[0]/\$pi) * 180 }my @core = ( 0 .. 1_000 ) ;my @sine ;my @cosine ;for my \$a ( @core ) {    push @sine   , sin(deg_to_rad(\$a)) ;    push @cosine , cos(deg_to_rad(\$a)) ;    }my \$cc = Chart::Clicker->new;my \$series1 = Chart::Clicker::Data::Series->new(    keys    => \@core ,    values  => \@sine    );my \$series2 = Chart::Clicker::Data::Series->new(    keys    => \@core ,    values  => \@cosine    );my \$dataset = Chart::Clicker::Data::DataSet->new(        series  =>      [ \$series1 , \$series2 ],    );\$cc->add_to_datasets(\$dataset) ;\$cc->write_output('graph_test.png');exit ;`

There's lots of ways to do graphs. The way we do some graphs here is to do a system call to R. R is powerful, sure, but there's no good way to set up a batch of complex graphs in Perl and send them to R for graphing. There are ways, sure, but not good ways. So, I expect to do a lot more with Chart::Clicker in the future.
