XHTML Family Tree Generator is a CGI Perl script together with some Perl modules that will create views of a family tree. Data can be stored in a database or in a data file. The data file is either a simple text (CSV), an Excel, or GEDCOM file listing the family members, parents, and other details. It is possible to show a tree of ancestors and descendants for any person, showing any number of generations. Other facilities are provided for showing email directories, birthday reminders, facehall, and more. It has a simple configuration, makes heavy use of CGI (and other CPAN modules), generates valid XHTML, and has support for Unicode and multiple languages.

It's a Java applet that communicates with an XML-RPC server to load the graph that is displayed.
