↓ INFO ↓
The result format graph, part of the Semantic Result Formats extension, can be used to display result values as a graph showing the relation between pages. In order to work the GraphViz extension is required to be installed, too.
For recent versions, you should install a recent version of GraphViz that in turn also needs ImageMap. Both should be installed with composer. The following should work with MW 1.24, SMW 2.0 and SRF 2.0. Go to the root directory of your MW installation. Then, depending on your composer installation, either type
composer require mediawiki/graph-viz '*' composer require mediawiki/image-map @dev
or
php composer.phar require mediawiki/graph-viz '*' php composer.phar require mediawiki/image-map @dev
Also make sur to remove any require_once("$IP/extensions/GraphViz/GraphViz.php"); line from LocalSettings.ini.
Bug (as of Dec 2015): The graphname=... will break the code and therefore should not be used.
