hi @crachel
When using open-street-map template, I get the relayoutData printed. For example, I get:
{‘mapbox.center’: {‘lon’: -99.88767635096002, ‘lat’: 33.130783012662036}, ‘mapbox.zoom’: 4.5, ‘mapbox.bearing’: 0, ‘mapbox.pitch’: 0, ‘mapbox._derived’: {‘coordinates’: [[-114.52354376038313, 38.785437325640004], [-85.25180894153786, 38.785437325640004], [-85.25180894153786, 27.08718413770059], [-114.52354376038313, 27.08718413770059]]}}
When I use your last piece of code, using open street map:

from dash.exceptions import PreventUpdate
import plotly.express as px
import pandas as pd
from plotly.graph_objects import Scattermapbox
from plotly.graph_objs.layout import Margin
app = Dash(__name__)
# assume you have a "long-form" data frame
# see https://plotly.com/python/px-arguments/ for more options
# df = pd.DataFrame({
# "Fruit": ["Apples", "Oranges", "Bananas", "Apples", "Oranges", "Bananas"],
# "Amount": [4, 1, 2, 2, 4, 5],
# "City": ["SF", "SF", "SF", "Montreal", "Montreal", "Montreal"]
# })
#
# fig = px.bar(df, x="Fruit", y="Amount", color="City", barmode="group")
app.layout = html.Div(children=[
html.H1(children='Hello Dash'),
html.Div(id='test-div', children='''
