Where are galaxy clusters situated within the cosmic web structure?

At the intersections/knots where filaments converge

Galaxy clusters are not randomly placed but form the nodes of the large-scale structure known as the cosmic web. This web is composed of filaments, sheets, voids, and walls of matter, including dark matter and baryonic matter. Galaxy clusters form specifically at the intersections, or 'knots,' where the long filaments of matter converge. These filaments act as cosmic highways, efficiently channeling galaxies and gas toward these high-density central meeting points, which eventually collapse and virialize under gravity to form the massive, bound cluster structure.
