What is relation between Holographic principle and Hologram?

The holographic principle is a property of quantum gravity and string theories which states that the description of a volume of space can be thought of as encoded on a boundary to the region—preferably a light-like boundary like a gravitational horizon.

The only similarity is that both the holographic principle and the way holograms work can be described as encoding the information necessary to reconstruct an $N$-dimensional view on an $N-1$-dimensional surface. But beyond that qualitative description, there are not any meaningful similarities.
