With respect to OWID, one can see the interactive graphs working within a mediawiki environment here. Our hope for next steps to get around the current blockers is to show a static version of the graph from Commons with a play button overlay. When the play button is hit a consent pop up similar to what you see for maps on Wikivoyage when you request a layer such as "relief maps". This will then bring in the corresponding interactive content hosted from the wmcloud. While this be acceptable to the powers that be? I am not sure.
