NAME
    HTML::TagCloud::Sortable - A sortable HTML tag cloud

SYNOPSIS
        my $cloud = HTML::TagCloud::Sortable->new;
    
        # old HTML::TagCloud style
        $cloud->add( 'foo', $url, 10 );
    
        # new HTML::TagCloud::Sortable style
        $cloud->add( { name => 'foo', url => $url, count => 10, bar => 'baz' } );
    
        # old style
        print $cloud->html( 4 );
    
        # new style
        print $cloud->html( { limit => 4, sort_field => 'count', sort_type => 'numeric' } );

DESCRIPTION
    HTML::TagCloud::Sortable is an API-compatible subclass of
    HTML::TagCloud. However, by using a different API, you can gain two
    features:

    *   Store arbitrary data with your tags

    *   Sort the tags by any stored field

METHODS
  new( %options )
    An overridden construtor. Takes the same arguments as HTML::TagCloud.

  add( \%tagdata )
    Adds the hashref of data to the list of tags. NB: Insertion order is
    maintained. At the minimum, you will need to supply "name", "url" and
    "count" key-value pairs.

  tags( \%options )
    This method is used by "html" to get the relevant list of tags for
    display. Options include:

    *   limit - uses the N most popular tags

    *   sort_field - sort by this field

    *   sort_order - 'asc' or 'desc'

    *   sort_type - 'alpha' or 'numeric'

    The default sort order is alphabetically by tag name. You can pass a sub
    reference to "sort_field" to do custom sorting. Example:

        $cloud->html( { sort_field =>
            sub { $_[ 1 ]->{ count } <=> $_[ 0 ]->{ count }; }
        } );

    Passing undef to sort_field will maintain insertion order.
