Visual Description
Image extracted from the Euclid Flagship simulations catalog. Each dot represents a galaxy: blue points mark galaxies at the centers of dark matter clumps, while red points denote satellites within them. These trace cosmic large-scale structure, which consists of clumps, filaments, and voids, in a web-like distribution.
