This presentation made me leave the page before the first graph, because bits would only start to appear half cut-off at the top of my window as I scrolled down. I'm using the latest version of out-of-the-box Firefox on a desktop, not some gimpy "browser" on a tiny phone or IE6 or heaps of functionality-destroying add-ons.
