【问题描述】：

我正在创建一个仪表板，我想使用这个交互式地图

网页链接：https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/causesofdeath/articles/deathsinvolvingcovid19interactivemap/2020-06-12

嵌入代码： <iframe height="1043px" width="100%" src="https://www.ons.gov.uk/visualisations/dvc914/map/index.html"></iframe>

现在我对 HTML 了解不多，但这是我目前所掌握的。我知道布局是错误的，但我已经被困了很长一段时间，谁能指出我正确的方向。非常感谢！

import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.express as px
import pandas as pd
from dash.dependencies import Input, Output

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)


#H1 = biggest heading,  Div = a box containhg info
app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),

    html.Div(children='''
        Dash: A web application framework for Python.
    '''),

    dcc.Graph(
        id='example-graph',
        figure=fig
        
    <iframe   src="https://www.ons.gov.uk/visualisations/dvc914/map/index.html"></iframe>
    )
])

if __name__ == '__main__':
    app.run_server(debug=True,port=8049,host='127.0.0.1')

【参考方案1】：

你快到了。只需将 iframe 元素的 语法替换为您用于其他元素的破折号语法，

import dash
import dash_core_components as dcc
import dash_html_components as html

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),

    html.Div(children='''
        Dash: A web application framework for Python.
    '''),

    dcc.Graph(
        id='example-graph',
        # figure=fig  # commented out to make the example runnable
    ),

    html.Iframe(src="https://www.ons.gov.uk/visualisations/dvc914/map/index.html",
                style="height": "1067px", "width": "100%")
])

if __name__ == '__main__':
    app.run_server(debug=True, port=8049, host='127.0.0.1')
