About Edge of the observable universe
The map lists it as a region / boundary (horizon) and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.
The particle horizon: the farthest distance from which light could have reached us in 13.8 billion years, 46.2 billion light-years today (14.16 Gpc comoving, Planck 2018). The observable universe is about 92 billion light-years across.

From Wikipedia
The observable universe is a spherical region of the universe consisting of all matter that can be observed from Earth; the electromagnetic radiation from these astronomical objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.
