History: GraphViz Install

            {syntax type="markdown"  editor="wysiwyg"} # Graphviz Install


Graphviz provides a collection of tools for manipulating graph structures and generating graph layouts.

{icon name=thumbs-o-up} For those who would like to use **Dynamic ((SiteMap))** graph generation in Tikiwiki, we recommend the Graphviz library and the ((PluginWikigraph)). GraphViz with Wikigraph plugin (in mods.tw.o) work well still with Tiki 3 LTS, but not with Tiki 6 LTS.

## Install Graphviz and Libs

- On Windows the default installer exe should do all necessary steps. 
     Get Graphviz from [http://graphviz.org/pub/graphviz/].
- On RPM based system (RedHat, Mandrake) 
     rpm -q graphviz
- On APT based system (Debian, Knoppix) 
     apt-get -s install graphviz
- For Portage users (Gentoo) 
     emerge graphviz

## Testing an installed Graphviz Setup

- {icon name=thumbs-o-up} Point your browser to [http://127.0.0.1/tiki-wiki_graph.php?page=HomePage&level=2]

## Troubleshooting Hints

- {icon name=warning} Graphviz consumes LOTS of memory with even small (no. of wikipages less than 100) wiki content. Try to keep the *Level* of the graph low in order to use wiki pages including dynamic graphs.
- {icon name=warning}If you use Windows, copy GraphViz binary files (dot.exe, neato.exe, etc) from the GraphViz bin folder to the windows\\system32 or equivalent folder (NaV/system32). The installer should have done this job for you, but we recommend double-checking if you encounter errors. It's not the same to put the exe's in the path, they must be in a Windows system directory.
- In PHP Safemode environments, special adjustments need to be made to use external libraries. 
    - These settings will be included here.
