Description of expected behavior and the observed behavior

Well the expectation is to see the rasterized image of the example dataset.

Complete, minimal, self-contained example code that reproduces the issue

import xarray as xr

ds = xr.tutorial.open_dataset('rasm')
ds.Tair.hvplot.quadmesh(x='xc', y='yc', geo=True, widget_location='bottom', rasterize=True)
