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 ▏
       # 1 ██████████▉
       # 2 █████████████████████▊
       # 3 ████████████████████████████████▋
       # 4 ███████████████████████████████████████████▌
       # 5 ██████████████████████████████████████████████████████▍

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.
