I'd like to announce an update of my graph extension - or for people who 
never heard of it, the existance of it :)

The extension is now one year old (actually, a bit older, but the first 
usable version was not available until Janua 2005 :) and quite mature.

An overview, examples, download links and install instructions are here:


There is also a detailed online manual about the syntax, attributes and 


The extension can create ASCII art, Unicode box drawings, HTML, SVG and 
PNG (via graphviz/dot/neato/fdb etc) output. It is most suited for 
flowcharts, state diagrams and documentation of information flow, but 
shold also be able to handle more complex graphs.

The syntax is designed to be easy for humans (readability/maintainability) 
and also easy to parse for machines. The output is indexable by search 
engines (except in case of PNG output, naturally), and scales with the 
text size in the browser, thus also supporting users with bad sight. It 
also falls back to simple renderings, like when you look at it with a 
textbrowser like lynx :)

If you have questions or problems, please do not hesitate to contact me, 
or open up a bugreport at http://rt.cpan.org.

Here are two examples straight from my console:

 # echo "[My Work] - internet -> [Your Success]"|perl examples/as_ascii
 +---------+  internet   +--------------+
 | My Work | ----------> | Your Success |
 +---------+             +--------------+
 # echo "[My Work] - internet -> [Your Success]"|perl examples/as_boxart
 ┌─────────┐  internet   ┌──────────────┐
 │ My Work │ ──────────> │ Your Success │
 └─────────┘             └──────────────┘
