NAME
HTML::TagCloud - Generate An HTML Tag CloudSYNOPSIS
my $cloud = HTML::TagCloud->new; $cloud->add($tag1, $url1, $count1); $cloud->add($tag2, $url2, $count2); $cloud->add($tag3, $url3, $count3); my $html = $cloud->html_and_css(50);
DESCRIPTION
The HTML::TagCloud module enables you to generate ``tag clouds'' in HTML. Tag clouds serve as a textual way to visualize terms and topics that are used most frequently. The tags are sorted alphabetically and a larger font is used to indicate more frequent term usage.Example sites with tag clouds: <http://www.43things.com/>, <http://www.astray.com/recipes/> and <http://www.flickr.com/photos/tags/>.
This module provides a simple interface to generating a CSS-based HTML tag cloud. You simply pass in a set of tags, their URL and their count. This module outputs stylesheet-based HTML. You may use the included CSS or use your own.
CONSTRUCTOR
new
The constructor takes one optional argument:my $cloud = HTML::TagCloud->new(levels=>10);
if not provided, levels defaults to 24
METHODS
add
This module adds a tag into the cloud. You pass in the tag name, its URL and its count:$cloud->add($tag1, $url1, $count1); $cloud->add($tag2, $url2, $count2); $cloud->add($tag3, $url3, $count3);
tags($limit)
Returns a list of hashrefs representing each tag in the cloud, sorted by alphabet. Each tag has the following keys: name, count, url and level.css
This returns the CSS that will format the HTML returned by the html() method with tags which have a high count as larger:my $css = $cloud->css;
html($limit)
This returns the tag cloud as HTML without the embedded CSS (you should use both css() and html() or simply the html_and_css() method). If a limit is provided, only the top $limit tags are in the cloud, otherwise all the tags are in the cloud:my $html = $cloud->html(200);
html_and_css($limit)
This returns the tag cloud as HTML with embedded CSS. If a limit is provided, only the top $limit tags are in the cloud, otherwise all the tags are in the cloud:my $html_and_css = $cloud->html_and_css(50);
