H3HexagonLayer in pydeck doesn't display #1229
Description
I previously posted this as a feature request but realized it's a bug.
Data loaded in an H3HexagonLayer in pydeck doesn't display. The data I'm hoping to visualize has lat long and hex features. Loading the lat longs into a HexagonLayer works, loading the hex feature into an H3HexagonLayer does not. There's no error message - the map displays with no data overlay. I ran the same code in a notebook without streamlit and it works as expected, so this isn't a pydeck bug.
Here's the relevant code:
st.write(
pdk.Deck(
mapbox_key='my_key',
map_style="mapbox://styles/mapbox/light-v9",
tooltip={"text": "Trips: {count}"},
initial_view_state=pdk.ViewState(
latitude=40.763781,
longitude=-111.894560,
zoom=10,
bearing=0,
pitch=50
),
layers=[
pdk.Layer(
"H3HexagonLayer",
df,
pickable=True,
stroked=True,
filled=True,
extruded=True,
get_hexagon="hex",
get_fill_color=f"[255, (1 - count / {max_count}) * 255, 0]",
get_elevation='count * 20',
get_line_color=[255, 255, 255],
line_width_min_pixels=2,
),
],
)
)
Here's df.head():
