DQ9-Alchemy-Dependency-Graphs is a project mainly written in PERL and SHELL, it's free.
This generates dependency graphs for each item in Dragon Quest 9 that can be made via alchemy.
This tiny Perl script will parse Zaraf's Alchmey Recipe Guide, from GameFAQs, and generate dot graphs of the dependencies.
You can find the latest version of this alchemy guide here: http://www.gamefaqs.com/ds/937281-dragon-quest-ix-sentinels-of-the-starry-skies/faqs/60451
To run this, you need:
1) A recent version of Perl. Fortunately, no external modules were used.
2) Graphviz - http://www.graphviz.org/ or sudo apt-get install graphviz
