Code:

import pandas as pd

import plotly.express as px 

df= pd.read_csv("sample_data.csv")

px.set_mapbox_access_token(open("mapbox_token").read())

    data_frame=df, lat="latitude", lon="longitude", color='TOT_POPULA',

    min_count=1
)
fig.update_layout(margin=dict(b=0, t=0, l=0, r=0))
fig.show()

Here is the dataset used above: sample_data.csv

@RenaudLN @nicolaskruchten Hi, since I see your contributions in PRs #2559 #2638, would it be possible to have a dekko here? We have been unable to figure out the root cause and haven't received any response on the Plotly community forum/Stack Overflow either.

@ragul-n you've got incorrect latitude and longitude values

This works

import pandas as pd
import plotly.figure_factory as ff
import plotly.express as px 

df = pd.read_csv("sample_data.csv")
        
fig = ff.create_hexbin_mapbox(
    data_frame=df.query("-90 <= latitude <= 90 & -180 <= longitude <= 180"), lat="latitude", lon="longitude", color='TOT_POPULA',
    agg_func=np.sum,  nx_hexagon=30,
    opacity=0.7, labels={"color": "Population"},
    show_original_data=False,
    original_data_marker=dict(size=1, opacity=0.6, color="deeppink"),
    min_count=1,
    mapbox_style="carto-darkmatter",
)
fig.update_layout(margin=dict(b=0, t=0, l=0, r=0))
fig.show()
