Wikipedia has a good description of the distribution of galaxies on this scale 

Universe Sphere: 380000 laser etched dots, each dot representing a galaxy of stars, reveals the largest scale structure of our universe. This glass sphere contains a 3D mapping of galaxies in a volume of our universe spanning 800 million lightyears in diameter, and matches the clumping and distribution as seen by automated telescopic surveys such as that found in the Sloan Digital Sky Survey data. Hold a chunk of the universe in your hand!
