Plotly create inset choropleth (Mapbox ideally) of Alaska and Hawaii

[empet]

@hillard28
I created a minimal working example of US map and an inset for Alaska. You have to add go.Choroplethmapbox for both US and Alaska, instead my go.Scattermapbox(es).

import plotly.graph_objects as go
from plotly.subplots import make_subplots

fig = make_subplots(
    specs=[[{'type': 'mapbox'}]],
    insets=[{'type': 'mapbox',
             'l':0.0,
             'w':0.25,
             'h':0.48}])


fig.add_trace(go.Scattermapbox(lon=[-101.29], lat=[42.11], marker_size=8))  # 47.1164° N, 101.2996° W
fig.add_trace(go.Scattermapbox(lon=[-150.49], lat=[64.80], subplot= "mapbox2"))  #64.2008° N, 149.4937° W

fig.update_layout(mapbox=dict(style="open-street-map", center_lon=-101.29, center_lat=42.11, zoom=1.75 ),
                 mapbox2=dict(style="open-street-map", center_lon =-150.49, center_lat=64.80, zoom=1.55))

These are the keywords for inset definition ( i got them printing help(make_subplots)

insets: list of dict or None (default None):
        Inset specifications.  Insets are subplots that overlay grid subplots
    
        - Each item in 'insets' is a dictionary.
            The available keys are:
    
            * cell (tuple, default=(1,1)): (row, col) index of the
                subplot cell to overlay inset axes onto.
            * type (string, default 'xy'): Subplot type
            * l (float, default=0.0): padding left of inset
                  in fraction of cell width
            * w (float or 'to_end', default='to_end') inset width
                  in fraction of cell width ('to_end': to cell right edge)
            * b (float, default=0.0): padding bottom of inset
                  in fraction of cell height
            * h (float or 'to_end', default='to_end') inset height
                  in fraction of cell height ('to_end': to cell top edge)

For your examples you have to choose an adequate 'w' (width) and 'h' (height) for the inset, and zoom value for each mapbox.
