DESCRIPTION
  METHODS
    Returns a string with a single utf8 bar according to the values

        Term::Vspark::show_bar($value_for_this_bar, $max_value, $number_of_columns_to_display);

    Returns a string with a various utf8 bars according to the values

        Term::Vspark::show_graph('values' => \@values_for_this_graph, 'max' => $max_value, 'columns' => $number_of_columns_to_display);

    Example:

        use Term::Vspark;
        use Term::Size;

        chomp( @ARGV = <STDIN> ) unless @ARGV;

        my @list = sort { $a <=> $b } @ARGV;
        my ($columns, $rows) = Term::Size::chars *STDOUT{IO};

        print Term::Vspark::show_graph(
            'max'     => $list[-1],
            'columns' => $columns,
            'values'  => \@ARGV,
        );

    Example 2:

        chomp( @ARGV = <STDIN> ) unless @ARGV;
        my %k_values = @ARGV;

        my @list = sort { $a <=> $b } values %k_values;

        print Term::Vspark::show_labeled_graph(
            'max'      => $list[-1],
            'columns'  => 10,
            'k_values' => \%k_values,
        );

    This will receive numbers from ARGV or STDIN and print out beutiful
    graph based on that data.
