I'm very new to Confluence and Gliffy, so maybe this is obvious but I'm banging my head against a wall with it.
I've created a Gliffy diagram in my page. The placeholder for Gliffy seems to fill the full width of the page, even when I change the width of the page, but the diagram always sits on the left hand side of.
So far I've tried resizing the diagram area, and trying to center align the surrounding paragraphs of the Gliffy placeholder.
