Rendered GraphGist page not new-user friendly

[cheerfulstoic]

Feedback from Ryan:

"we also really need to make sure people understand how GraphGists work. Right now, when you click on the 'play' icon on a GraphGist, there's no UX feedback to indicate what is happening. Sometimes the console is at the top of the page, and sometimes it's at the bottom, and we don't scroll or indicate in any way what happens when you click on play. Let's take a look at this from a "new user" perspective and make sure it's clear what's happening."
