Every dot in this image is a galaxy, not a star. You can see the distribution of dark matter in this image and the images before, but it's almost the same as the distribution of galaxies. Even this image still covers a huge area; from left to right it's a distance of approximately 45 million light years; the 2 Mpc/h represent almost 9 million light years. Remember that the Andromeda Galaxy is just 2.5 million light years away and the Large Magellanic Cloud only 160 000 light years.
Finally we have two videos for you. The first one shows a flight through the Millenium Simulation at a fixed point of time. The second shows a simulation of the evolution of the universe from the beginning up to today.
