There are attempts, but they all suck IMHO :( Someday I'll get around to doing this in Three.js for real, if no one beats me to it. It's shocking that we have a million 3D sites to visualize LEO satellites and plenty to visualize the solar system, but our stellar (much less galactic!) neighborhood is all super outdated stuff only.

I guess the sad reality is that these tools aren't that useful for anything but diagramming the odd interstellar rock.
