Graphs in the DOT and mscgen languages may include URLs. No preparse option will lead to two images, in case of a change to the original, of which the older version will always be imported should the template be called.ДЇor graphviz, use unique names for each graph to display multiple graphs on the same page.ДЇor mscgen, use the 'uniquifier' tag attribute to display multiple message sequence charts on the same page. Changes to the original template will then be passed on. The option preparse='dynamic' makes it also possible to use GraphViz and templates and import these into a MediaWiki site.

When the wiki page is saved (or when you click 'Show preview' after editing) an image is produced that corresponds to the DOT or mscgen text and it is shown in-line on the page. You may define a message sequence chart in the mscgen language and enclose it in mscgen tags as follows: You may define a graph in the dot language and enclose it in graphviz tags as follows: If graphs or message sequence charts do not render then you may need to tune these settings for your installation. Note: Under Linux, shell commands such as the Graphviz and mscgen executables are invoked with the limits given by $wgMaxShellTime, $wgMaxShellMemory and $wgMaxShellFileSize. Path of the directory containing the Graphviz executables (dot, circo, fdp, neato, twopi)Дefault output image type if none is specified on the 'format' attribute of an individual graph Path of the directory containing the Graphviz executables (dot.exe, circo.exe, fpdp.exe, neato.exe, twopi.exe) Set configuration parameters in LocalSettings.php only if the defaults do not suit your environment. Make sure that internet users get read/execute access on your executables if you use server installations (especially under Windows).Make sure that write permissions for the '$IP/images' directory are granted.Once you have Composer properly installed, go to your MediaWiki installation directory and add the extension to your to your :
