Visualisation of the datasets in 3-dimensional Cartesian coordinates: photometric galaxies described as lines of sight (green lines), perpendicular filamentary spines (darkblue spines), non-perpendicular filamentary spines (orange spines), and spectroscopic galaxy lines of sight (red lines). All the drawn objects are located in the distance range of 200− 600 Mpc, and on the sphere, they are located at a maximum distance of 8 degrees from a randomly chosen filamentary spine of the filament catalogue. The photometric galaxy lines of sight are randomly chosen to be 0.25% and the spectroscopic galaxy lines of sight are a randomly chosen to be 0.5% of those in the selected region.
