Works for me, could you report your versions?

[ColinTalbert]

I get the same error. Windows 10,

print("gbd", gpd.__version__)
print("hvplot", hvplot.__version__)

gbd 0.4.0
hvplot 0.2.1

[ahuang11]

Also Windows 10 Subsystem Linux: hvplot 0.2.1.post5+gcba25ba.dirty gpd 0.4.0

[philippjfr]

Thank you both, I was still on geopandas 0.3.0, which does work. Will probably need to make some updates in geoviews.

[philippjfr]

Figured out the issue, nothing to with versions. Simply have to make sure that geoviews is imported, otherwise the geopandas interface isn't loaded and it simply won't understand the data.

I'll make a PR on hvplot which does the import for you.
