And I'm trying to create a choropleth using the following code, nonetheless the map that is displayed is not showing nothing

import plotly.express as px
import requests
repo_url = 'https://raw.githubusercontent.com/angelnmara/geojson/master/mexicoHigh.json' 
#Archivo GeoJSON
mx_regions_geo = requests.get(repo_url).json()

fig = px.choropleth(data_frame=data, 
                    geojson=mx_regions_geo, 
                    locations='estado', # nombre de la columna del Dataframe
                    featureidkey='properties.name',  # ruta al campo del archivo GeoJSON con el que se hará la relación (nombre de los estados)
                    color='percentage', #El color depende de las cantidades
                    color_continuous_scale="burg", #greens
                    #scope="north america"
                   )

fig.update_geos(showcountries=True, showcoastlines=True, showland=True, fitbounds="locations")
fig.show()

What I want is a map from Mexico that shows color scale according to the value on percentage column. I'm verynew to plotly so any help would be great

Your problem turned out to be the fact that the estada names in your data object are not capitalized, whereas they are capitalized in mx_regions_geo. Below, the data object is first converted to a data frame. Then the names of the estada are capitalized.

df = pd.DataFrame({'estado': data['estado'].values(), 'percentage':   data['percentage'].values()})
Kdf['estado'] = df['estado'].str.capitalize()

fig = px.choropleth(data_frame=df, 
                    geojson=mx_regions_geo, 
                    locations=df['estado'], # nombre de la columna del Dataframe
                    featureidkey='properties.name',  # ruta al campo del archivo GeoJSON con el que se hará la relación (nombre de los estados)
                    color=df['percentage'], #El color depende de las cantidades
                    color_continuous_scale="burg",
                    #scope="north america"
                   )

fig.update_geos(showcountries=True, showcoastlines=True, showland=True, fitbounds="locations")
fig.show()

Example with plotly.graph_objects and Mapbox.

import plotly.graph_objects as go
fig = go.Figure(go.Choroplethmapbox(name='Mexico', geojson=mx_regions_geo, ids=df['estado'], z=df['percentage'],
                                  locations=df['estado'], featureidkey='properties.name', colorscale='reds',
                                  marker=dict(line=dict(color='black'), opacity=0.6)))
fig.update_layout(mapbox_style='open-street-map',
                  mapbox_zoom=4, 
                  mapbox_center = {'lat': 25, 'lon': -99}
                 )
fig.update_layout(margin={"r":0,"t":0,"l":0,"b":0})
fig.show()
