This site's Content-Security-Policy restricts embedding to specific origins ("frame-ancestors 'self' flashcardmachine.com *.flashcardmachine.com *.coursehero.com *.cliffsnotes.com *.bartleby.com *.ipl.org *.scribbr.com"), which does not include StatsMyWeb.
Since coursehero.com can't be embedded live, this is a captured screenshot instead — a snapshot from whenever it was last rendered, not necessarily this exact moment.
