I know this is listed as unmaintained, and the extension link itself is broken, but is anyone out there using this? Is there a version somewhere else that is getting some use? Thanks!

Version and Usage Matrix lists two wikis that use this extension on 1.35: https://wikiapiary.com/wiki/Extension:Semantic_MediaWiki_Graph
Thanks. That leads me to wonder where they are getting it from or if they just happen to have an old version installed that has endured a few upgrade cycles.
Download seems to work when clicking the link. But also have not tested it on MW 1.37, yet.
I gave up trying to get this extension to work on my 1.35.
I found a good alternative in VIKI which from 1.27 to 1.33 no longer worked but now seems to do its job well.
There has been some activity here: https://github.com/krabina/Semantic-MediaWiki-Graph Feel free to join in the effort.
