=head1 Synopsis

Take a data structure in Perl, and automatically write a Python3 script using matplotlib to generate an image.  The Python3 script is saved in C, to be edited at the user's discretion.
Requires python3 and matplotlib installations.

My aim is to simplify the most common tasks as much as possible.  In my opinion, using this module is much easier than matplotlib itself.

=head1 Single Plots

Simplest use case:

 use Matplotlib::Simple;
 bar({
    'output.file'     => '/tmp/gospel.word.counts.png',
    data              => {
       Matthew => 18345,
       Mark    => 11304,
       Luke    => 19482,
       John    => 15635,
    }
 });

A more complete (and slightly faster execution):

 use Matplotlib::Simple;
 plt({
    'output.file'     => '/tmp/gospel.word.counts.png',
    'plot.type'       => 'bar',
    data              => {
       Matthew => 18345,
       Mark    => 11304,
       Luke    => 19482,
       John    => 15635,
    }
 });

=head1 Multiple Plots

Having a C argument as an array lets the module know to create subplots:

 use Matplotlib::Simple 'plt';
 plt({
     'output.file'   => 'svg/pies.png',
     plots             => [
     {
             data    => {

C, C, C, C, C, C, C, C, C, C, and C all match the methods in matplotlib itself.

=head2 Options

C and C are both implemented at the plot, rather than subplot, level.  See Matplotlib's documentation for more clarity.
