Choropleth Africa map doesn't show some countries and islands

Hi @Joicy
The answer is in this post (“bumping the resolution to 50m should do the trick”). fig_map.update_layout(geo_scope="africa", geo_resolution=50)

If you want Seychelles to appear, you’ll have to change the scope to world.

Using your same data:
https://raw.githubusercontent.com/joicy/bioinfo/main/df_map_last_frame.csv

import pandas as pd
import plotly.express as px

df_map = pd.read_csv("data.csv")

fig_map = px.choropleth(df_map,
                        locations='sov_a3', color='cum_counts',
                        hover_name='country', animation_frame="date_2weeks",
                        color_continuous_scale="algae",
                        range_color=[0, max(df_map['cum_counts'])],
                        labels={'cum_counts': 'Number of genomes'}
                        )
fig_map.update_layout(geo_scope="africa", geo_resolution=50)
fig_map.show()

P.S. you don’t need graph_objects here.
