problem plotting labels with `geo=True`
ALL software version info
(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc) hvplot 0.7.1 holoviews 1.14.2 geoviews 1.9.1
Description of expected behavior and the observed behavior
This is related to an issue I responded to on StackOverflow.
I would expect this to work:
gdf.hvplot.labels(text="labels", geo=True)
Complete, minimal, self-contained example code that reproduces the issue
import geopandas as gpd
import pandas as pd
import hvplot.pandas
import geoviews as gv
from geoviews import tile_sources as gvts
raw = """8911 POINT (5.79557 53.20121)
8912 POINT (5.76973 53.18031)
8913 POINT (5.78159 53.20088)
8914 POINT (5.75442 53.20394)
8915 POINT (5.76594 53.21173)"""
data = [(_[0], _[-2], _[-1]) for _ in [_.replace("(", "").replace(")", "").split() for _ in raw.split("\n")]]
df = pd.DataFrame(data, columns=["labels", "x", "y"]).astype({"labels": str})
gdf = gpd.GeoDataFrame(df, geometry=gpd.points_from_xy(df.x, df.y, crs="EPSG:4326"))
tiles = gvts.CartoLight
points = gdf.hvplot(geo=True, tiles="CartoLight")
# This doesn't work, but I would think it should:
labels = gdf.hvplot.labels(text="labels", geo=True)
# This works, but seems like a work-around:
# labels = gdf.to_crs("EPSG:3857").assign(x=lambda df: df.geometry.x, y=lambda df: df.geometry.y).hvplot.labels(text="labels", x="x", y="y")
(points * labels * tiles).opts(height=600, width=800)

Below is the error message I encountered, OP encountered a different error.
