NAME
       GraphViz::XML - Visualise XML as a tree

SYNOPSIS
         use GraphViz::XML;

         my $graph = GraphViz::XML->new($xml);
         print $g->as_png;

DESCRIPTION
       This module makes it easy to visualise XML as a tree. XML is hard for
       humans to grasp, especially if the XML is computer-generated. This
       modules aims to visualise the XML as a graph in order to make the
       structure of the XML clear and to aid in understanding the XML.

       XML elements are represented as diamond nodes, with links to elements
       within them. Character data is represented in round nodes.

       Note that the XML::Twig module should be installed.

METHODS
   new
       This is the constructor. It takes one mandatory argument, which is the
       XML to be visualised. A GraphViz object is returned.

         my $graph = GraphViz::XML->new($xml);

   as_*
       The XML can be visualised in a number of different graphical formats.
       Methods include as_ps, as_hpgl, as_pcl, as_mif, as_pic, as_gd, as_gd2,
       as_gif, as_jpeg, as_png, as_wbmp, as_ismap, as_imap, as_vrml, as_vtx,
       as_mp, as_fig, as_svg. See the GraphViz documentation for more
       information. The two most common methods are:

         # Print out a PNG-format file
         print $g->as_png;

         # Print out a PostScript-format file
         print $g->as_ps;

BUGS
       GraphViz tends to reorder the nodes. I hope to find a work around soon
       (possibly with ports).
