Three years ago, you claimed to have created a 3D map of the observable universe and that it would be publicly available. Where is the specific hyperlink? Your Website so far gives only data table programming information and general analyses on features endemic to radiation.

In addition it has to be an interactive 3D map due to a more useful functionality, and is a more fundamental solution to 3D measurement. Given the data it isn't far at all to plot these using coordinates generalized spherically (which is how constellations are measured using Earth's coordinates).

"First Cosmology Results from DESI

DESI has created the largest 3D map of our universe. The Universe’s expansion history is now known to better than 1% precision, yielding the best picture yet of how the universe has evolved over the past 11 billion years. Read more in our announcement and the BerkeleyLab Press Release. Our results were presented at the APS and Moriond meetings as well as on Youtube."

Methods to access the underlying public data are documented at https://data.desi.lbl.gov/doc/access/ , in particular the full catalog is in this FITS-format file https://data.desi.lbl.gov/public/edr/spectro/redux/fuji/zcatalog/zall-pix-fuji.fits [2 GB] where the coordinates RA(right ascension), DEC(declination), Z(redshift) give the coordinates.  At the same time, the DESI survey has continued to map more of the universe and will continue to periodically release larger maps (the next is planned for sometime in 2025).

Our datasets are primarily intended for professional academic astronomers.  A more user-friendly distillation of the data for amateur astronomers and people interested in visualization is described at https://data.desi.lbl.gov/doc/releases/edr/vac/epoviz/ .  e.g. this was used to generate the video at https://www.youtube.com/watch?v=xdJWHXJCxpE [Credit David Kirkby].
