The Euclid telescope, just launched today, will be able to observe galaxies out to 10 billion light-years. Here's the largest map I could find (1 billion light years) that includes the Milky Way, Laniakea, the Shapley supercluster, the Perseus–Pisces supercluster, and the South Pole Wall.

The reason it isn't presented geometrically, by the way, is because over such upsettingly huge distances "geometry" loses some meaning. The current position of everything is more a view through time than actual space. So the map of the universe is much more like a timeline than an explorable map.

At the scale of the map up top, a billion years more or less won't make a huge difference, so it makes fair sense to present it that way. But once you're up to 100 Gy and beyond... shit gets weird.
