I cant find info as to generate charts for Bugzilla issues in Mediawiki, do we have any extension or way to achieve this?

No, and this is probably the wrong way to go.

First, find a package external to MediaWiki capable of doing that, then include it in MediaWiki by embedding it inside an iframe or something like this with the help of Extension:Widgets

See Extension:Bugzilla (but not sure if that functionality is already included)
