Python - plotly - 结合气泡和等值线图

Question

在这个问题的回答中R - plotly - combine bubble and chorpleth map ，它很好地描述了如何在 plotly 中将气泡图和等值线图组合在一张 map 中。我想在 Python 中复制完全相同的示例，但是我没有根据绘图文档 (https://plot.ly/python/reference/) 中提供的信息进行管理。

等效的 R 代码如下:

lon = c(-73.9865812, -118.2427266, -87.6244212, -95.3676974)
pop = c(8287238, 3826423, 2705627, 2129784)
df_cities = data.frame(cities, lat, lon, pop)

state_codes = c("NY", "CA", "IL", "TX")
pop = c(19746227.0, 38802500.0, 12880580.0, 26956958.0)
df_states = data.frame(state_codes, pop)

plot_ly(df_cities, lon=lon, lat=lat, 
        text=paste0(df_cities$cities,'<br>Population: ', df_cities$pop), 
        marker= list(size = sqrt(pop/10000) + 1), type="scattergeo",
        filename="stackoverflow/choropleth+scattergeo") %>%
  add_trace(z=df_states$pop,
            locations=df_states$state_codes, 
            text=paste0(df_states$state_codes, '<br>Population: ', df_states$pop),
            type="choropleth", 
            colors = 'Purples', 
            locationmode="USA-states") %>%
  layout(geo = list(scope="usa"))

这如何在 Python 中实现？

只需将 .py 附加到图形的 URL(例如 https://plot.ly/~RPlotBot/1735.py)即可查看相应的 python 代码。
