Description of expected behavior and the observed behavior

The example from https://hvplot.holoviz.org/user_guide/Geographic_Data.html should work. However, it gives a stack trace.

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

import xarray as xr
import hvplot.pandas  # noqa
import hvplot.xarray  # noqa
import cartopy.crs as ccrs
try:
    from bokeh.sampledata.airport_routes import airports
except:
    # This is run when the bokeh sample data hasn't been downloaded yet
    import bokeh
    bokeh.sampledata.download()
    from bokeh.sampledata.airport_routes import airports
airports.head(3)
airports.hvplot.points('Longitude', 'Latitude', geo=True, color='red', alpha=0.2,
                       xlim=(-180, -30), ylim=(0, 72), tiles='ESRI')

Stack traceback and/or browser JavaScript console output

When the above code is run in a JupyterLab notebook, it gives...

Are you sure that's the right environment you posted? You don't seem to have the necessary dependencies installed (e.g. geoviews is not there).

[MBetters]

My bad, re-exported my env and attached condaenv.yml.txt

[MBetters]

Ok, just retried and it worked. I must've gotten confused and used the old env.

Thanks for reporting back!
