GD::Chart::Radial is a Perl module that allows you to plot and output Radial or Radar charts using the GD library. The module is based on GD::Graph in how it can be used where possible.
A radial chart has multiple axis spread out from the centre, like spokes on a wheel. Each axis represents a particular measurement. Values are plotted by marking the value for what is being measured on each axis and optionally joining these points. The result can look like a spiderweb or a radar depending on how you plot the values.
my $chart = GD::Chart::Radial->new($width, $height);
$chart->set(title=>"This is a chart");
print OUTFILE $chart->png;
