The Sloan Digital Sky Survey (SDSS)
(see also Wikipedia) has
produced the most detailed 3D map of the universe so far. It contains
images, optical spectra,
infrared spectra, IFU
(integral field units) spectra
stellar library spectra and catalog data.
The new data release is the sixteen'th so far and is
dubbed DR 16.
The data can be accessed here.
The visualization can be done with
Marvin a tool to
visualize MaNGA data.
Here is the Sloan 2.5 m telescope
in Sunspot in the Sacramento Mountains of New Mexico.

This telescope can shoot sharply focused images from an area of three degrees (30 full moons).
Unlike other telescopes which are covered in domes, to avoid heat and so air fluctuations,
the telescope is at night removed from its housing.
Livescience: Scientists unveil largest 3D map of the universe ever:
After five years of peering into the deepest reaches of space, researchers have
released what they call the "largest three-dimensional map of the universe" ever.
No, you cannot see your house. The mind-boggling map is the result of an ongoing
project called the Sloan Digital Sky Survey (SDSS) - an ambitious, international
quest to map the expansion of the observable universe, and hopefully solve a few
cosmic conundrums in the process. With this newest update, the project has mapped
and measured more than 2 million galaxies, stretching from our Milky Way to
ancient objects more than 11 billion light-years away.
