NAME
    Map::Tube::Kazan - Interface to the Kazan Metro Map.

SYNOPSIS
     use Map::Tube::Kazan;
     my $obj = Map::Tube::Kazan->new;
     my $routes_ar = $obj->get_all_routes($from, $to);
     my $lines_ar = $obj->get_lines;
     my $station = $obj->get_node_by_id($station_id);
     my $station = $obj->get_node_by_name($station_name);
     my $route = $obj->get_shortest_route($from, $to);
     my $stations_ar = $obj->get_stations($line);
     my $metro_name = $obj->name;
     my $xml_file = $obj->xml;

DESCRIPTION
    It currently provides functionality to find the shortest route between
    the two given nodes.

     # Pragmas.
     use strict;
     use warnings;

     # Modules.
     use Encode qw(decode_utf8 encode_utf8);
     use Map::Tube::Kazan;

     # Object.
     my $obj = Map::Tube::Kazan->new;

     # Get route.
     my $route = $obj->get_shortest_route(decode_utf8('Яшьлек'), decode_utf8('Горки'));

     # Print out type.
     print "Route: ".encode_utf8($route)."\n";

     # Output:
     # Route: Яшьлек (Центральная линия), Козья слобода (Центральная линия), Кремлёвская (Центральная линия), Площадь Габдуллы Тукая (Центральная линия), Суконная слобода (Центральная линия), Аметьево (Центральная линия), Горки (Центральная линия)

     my $xml_file = $obj->xml;

     # Print out XML file.
     print "XML file: $xml_file\n";

             'driver' => 'neato',
             'tube' => $obj,
     ); 

     # Get graph to file.
     $g->graph('Kazan.png');

     # Print file.
     system "ls -l Kazan.png";
