The Graphical Category Browser extension shows the interconnection of categories as a graph enhances navigability of the site.

What this extension does

• A special page "Graphical Categories Browser" is added.
• A graph is added on top of each category page showing the relationships to other categories.

Images are file cached. Cache control to match HTML and image output is supplied.

Installation

• Install Graphviz - Graph Visualization Software.
• Download script and copy to extensions.
• Correct $xyDotPath and $xyCategoriesCache to your needs.
• Create directory images/xyGraphvizCache
• Add the following line to LocalSettings.php

require_once("$IP/extensions/xyCategoryBrowser/xyCategoryBrowser.php");

To change the design you may override entries in the following array:

$xyCategoryGraphStyle = array(
  "COLOR_NODE"          => "#EEEEEE", // color of category nodes
  "COLOR_NODE_ERROR"    => "#FF0000", // color for internal error
  "COLOR_NODE_REDIRECT" => "#FFCCCC", // color of redirected category nodes
  "COLOR_NODE_MISSING"  => "#FFFFCC", // color of missing category nodes
  "COLOR_LINK_REDIRECT" => "#FF0000", // color of redirect links
  "HEIGHT"              => "1920",    // height in pixels (96th of an inch)
  "WIDTH"               => "768"      // width in pixels (96th of an inch)
);
