NAME
    Term::Vspark

SYNOPSIS
        use Term::Vspark qw/show_graph/;
        binmode STDOUT, ':encoding(UTF-8)';
        print show_graph(
            values  => [0,1,2,3,4,5],
            labels  => [0,1,2,3,4,5], # optional
            max     => 7,             # optional
            columns => 80,            # optional
        );

        # The output looks like this:
        # 0 â
        # 1 âââââââââââ
        # 2 ââââââââââââââââââââââ
        # 3 âââââââââââââââââââââââââââââââââ
        # 4 ââââââââââââââââââââââââââââââââââââââââââââ
        # 5 âââââââââââââââââââââââââââââââââââââââââââââââââââââââ

DESCRIPTION
    This module displays beautiful graphs in the terminal. It is a companion
    to Term::Spark but instead of displaying normal sparklines it displays
    "vertical" sparklines.

    Note that because the graph is built from utf8 characters, users must
    setup UTF-8 encoding for STDOUT if they wish to print the output.

NAME
    Term::Vspark - Displays a graph in the terminal

METHODS
  show_graph( values => \@values, labels => \@labels, max => $max, columns => $columns )
    show_graph returns a string.

    The 'values' parameter should be an ArrayRef of numbers. This is
    required.

    The 'labels' parameter should be an ArrayRef of strings. This is
    optional. Each label will be used with the corresponding value.

    The 'max' parameter is the maximum value of the graph. Without this
    parameter you cannot compare graphs because the scaling will change
    depending on the data. This parameter is optional.

    The 'columns' parameter is the maximum width of the graph.
