Extension talk:SiteGraph

In MW 1.19.1 GraphViz extension is working correctly, but SiteGraph extension is not showing anyting, even in a test site with only 4 linked pages (a main page with links to three pages)

Changes in Script due to GraphViz Update
I am using the newest Version of Graphviz and had to modify the SiteGraph.php-Script, to make sure there won't be any Imagemap-errors. This is what I modified:

I changed the URL-Part in Line 126 from URL=\"". $title->getLocalURL. "\"];"; to  URL=\"" . $title . "\"];";

Error using the example
Graphviz is working fine, but when I try to use the example shown on the page, I get the following error, " Error: No valid link was found at the end of line 2. ". Using GraphViz(3.1.0) & MW(1.31.1) -- Bryandamon (talk) 23:15, 21 March 2019 (UTC)
