app.scripts.append_script({
    'external_url': 'https://api.mapbox.com/mapbox-gl-js/v2.6.1/mapbox-gl.js'
})

import dash_core_components as dcc

from dash.dependencies import Input, Output

    zoom = figure['layout']['mapbox']['zoom']
    center = figure['layout']['mapbox']['center']
    
    return f"当前缩放：{zoom}，当前居中：{center}"
