Extensions

Graphviz

Main page: Extension:GraphViz

Required: Graphviz webpage or direct file link

• version 2.18

Some Windows operating systems may require run-time components of Visual C++ libraries to properly run Graphviz executables. click this link and install Microsoft Visual C++ 2005 Redistributable Package (x86).

Install directions

1.) install graphviz software I installed it to w:\graphviz2.18

• this path is referenced in the graphviz.php and needs to be changed to your install path

2.) add user rights

• use file browser and find cmd.exe and give internet users read/execute access
• give internet users read/execute access to the directory graphviz was installed to

3.) create Graphviz.php

• save into your mediawiki/extensions folder
• edit about line 12 ( $wgGraphVizSettings->dotCommand = "w:\\graphviz2.18\\bin\\dot.exe"; ) to reflect your graphviz software installation
  • note the two "\\" between directories

<?php

# CoffMan (http://www.wickle.com) code adapted from timeline extension.

# To use, include this file from your LocalSettings.php
# To configure, set members of $wgGraphVizSettings after the inclusion

	if ( ! is_dir( $dest ) ) { mkdir( $dest, 0777 ); }

	}
	return $txt;
}

?>

4.) edit mediawiki localsettings.php

• add the following 2 lines:

include("extensions/Graphviz.php");

$wgGraphVizSettings->dotCommand = "W:\\Graphviz2.18\\bin\\DOT.exe";

• • change the dotcommand path to reflect your graphviz software installation
  • note the two "\\" between directory names

Graph with links assigned to each

use

node [URL="http://10.0.0.3//index.php?title=\N"];

where " title=\ " = " title=namespace\ "

where " \N" " will become the page title and is derived from the chart values

File:Graphviz with links

<graphviz>
digraph G {
node [style=filled, color=black, fillcolor=ghostwhite];
bgcolor="transparent";
node [URL="http://www.mediawiki.org/w/index.php?title=User:Mlong212/\N"];
size ="8,8";
Top[shape=box, style=filled, fillcolor=lightblue];
Bottom [style=filled, fillcolor=lightblue];
Top -> Branch1;
Top -> Branch2;
Top -> Branch3];
Branch1 -> sub1;
Branch2 -> Bottom;
sub3 -> "almost there";
Branch3 -> sub3;
sub1 -> Bottom;
"almost there" -> Bottom;
