We could generalize further and say that's what the entire window manager of an OS represents. Though, there's a difference between 'currently loaded' and just the address, and for less-than-high-end computers, that difference can mean a lot. That graph also contains a lot of noise - e.g. documents that aren't needed. I wonder if VR would help, by letting us see more, or if that better paradigm could also be implemented on 2D screens. There's already various graph visualization tools. But the tricky part would be wrapping that up into something useful - like a tree graph vs. tree style tabs. And if this would be more than 1-dimensional, like TST, then it would likely have to be a full page.
