在 Jupyter Notebook 中的 plotly scattergeo 图中为每个数据点嵌入 URL？

Posted 2023-01-13

我正在Jupyter notebook中使用plotly创建一个电台地图。我的目标是能够将其导出为html文件，然后嵌入到网站上。下面的例子（绘制点，保存.html文件）和我目前所做的很相似。

我想为每一个点嵌入超链接，无论是在悬停文本中还是在点本身上，当图形保存为html文件时，这些链接将持续存在。可以做到吗？

import plotly.graph_objects as go

import pandas as pd

df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/2011_february_us_airport_traffic.csv')
df['text'] = df['airport'] + '' + df['city'] + ', ' + df['state'] + '' + 'Arrivals: ' + df['cnt'].astype(str)

fig = go.Figure(data=go.Scattergeo(
        lon = df['long'],
        lat = df['lat'],
        text = df['text'],
        mode = 'markers',
        marker_color = df['cnt'],
        ))

fig.update_layout(
        title = 'Most trafficked US airports<br>(Hover for airport names)',
        geo_scope='usa',
    )
fig.show()
plotly.offline.plot(fig, filename='examplemap.html')

答案

取得了一些进展...

添加 import plotly.graph_objects as go 到前言，然后添加。

fig.add_trace(go.Scattergeo(
    lat=[40.678306],
    lon=[-105.040889],
    marker=
        "color": ["Crimson"],
        "line": 
            "width": 1
        ,
        "size": 10
    ,
    mode="markers+text",
    name="",
    text=[ "<a href=\"https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwv/\">WWV</a>"],
    textfont=
        "color": ["Crimson"],
        "family": ["Droid Sans, sans-serif"],
        "size": [22]
    ,
    textposition=["top center"]
))

还得把这个整合到for循环中去 但它确实能生成链接并有效地输出到HTML中去
