Graph-Easy

This module lets you create graphs (nodes/vertices connected by edges/arcs, not pie charts!) and then lay them out on a flat surface.

Once laid out, the graph can be converted into various output formats like ASCII art, HTML or SVG. You can also output the graph in graphviz format and let dot/neato/circo etc. do the layout for you.

Graphs can be either generated by Perl code, parsed from a simple text format that is human readable and maintainable, or parsed from Graphviz code.

For instance this input:

[ Bonn ] -> [ Berlin ]
[ Berlin ] -> [ Frankfurt ] { border: 1px dotted black; }
[ Frankfurt ] -> [ Dresden ]
[ Berlin ] ..> [ Potsdam ]
[ Potsdam ] => [ Cottbus ]

would be rendered in ASCII as:

+------+     +--------+      .............     +---------+
| Bonn | --> | Berlin |  --> : Frankfurt : --> | Dresden |
+------+     +--------+      .............     +---------+
               :
               :
               v
             +---------+     +---------+
             | Potsdam | ==> | Cottbus |
             +---------+     +---------+

The HTML or SVG output would look similiar except be more pretty :o)

Manual

The manual is contained in the extra package Graph::Easy::Manual, which also contains a Pod2HTML converter, that can handle embedded graphs in POD files.

You can also view the manual online at:

Many more examples and documentation, especially on integrating this into a Mediawiki installation, can be found at:

Have fun!

SVG Output

You also might want to install Graph::Easy::As_svg from CPAN, it provides you with the ability to generate SVG (Scalable Vector Graphics) files.

Installation
