@smcguire-cmu I played more! It gave me empty plot when I tried to do it for ALLWISE:

import hipscat

catalog = hipscat.loaders.read_from_hipscat('https://data.lsdb.io/unstable/wise/allwise')
hipscat.inspection.plot_points(catalog)

It also uses a lot of RAM, but it is probably expected?

Zoomed version works fine

import hipscat
from astropy.coordinates import Angle, SkyCoord

catalog = hipscat.loaders.read_from_hipscat('https://data.lsdb.io/unstable/wise/allwise')
hipscat.inspection.plot_points(catalog, center=SkyCoord(0, 0, unit='deg'), fov=(Angle(5, 'deg'), Angle(10, 'deg')))

@smcguire-cmu One more thing. It would be nice to make a "view window" to be a rectangle when fov is passed
