There are no filliments and not really any true voids either, just w whole lot of randomly placed Galaxies...
SE does show the large scale structure of galaxies with proper filaments and voids (though the distribution could be more realistic). The structure is not immediately obvious unless you fly at high speed and watch the relative density of galaxies around you (voids appear as long stretches of essentially nothingness), or increase the galaxy magnitude limit a lot (I recommend 17 to see it well).
You just have to realize that filaments and voids are a lot harder to discern in three dimensions from within (especially in true scale and brightness) than it is in a 2D slice as in most illustrative images.
