向 Folium 地图添加标题或文本

Question

我想知道是否有办法在 python 中的大叶地图上添加标题或文本？

我有 8 张地图要显示，我希望用户无需单击标记即可知道他们正在查看哪张地图。我试图添加地图的图像，但不能，因为我没有足够高的声誉分数。

我的代码：

#marker cluster
corpus_chris_loc = [27.783889, -97.510556]

harvey_avg_losses_map = folium.Map(location = corpus_chris_loc, zoom_start = 5)

marker_cluster = MarkerCluster().add_to(harvey_avg_losses_map)

#inside the loop add each marker to the cluster
for row_index, row_values in harvey_losses.iterrows():

    loc = [row_values['lat'], row_values['lng']]
    pop = ("zip code: " + str(row_values["loss_location_zip"]) + "\nzip_avg: " + "$" + str(row_values['zip_avg'])) #show the zip and it's avg
    icon = folium.Icon(color='red')
    marker = folium.Marker(
        title = "Harvey: " + "$" + str(row_values['harvey_avg']),
        location = loc, 
        popup = pop,
        icon=icon) 

    marker.add_to(marker_cluster)


#save an interactive HTML map by calling .save()

harvey_avg_losses_map.save('../data/harveylossclustermap.html')

harvey_avg_losses_map[map of hurricane harvey insurance claims][1]

当然，您可以为 Folium 地图添加标题。

例如：

import folium

loc = 'Corpus Christi'
title_html = '''
             <h3 align="center" style="font-size:16px"><b>{}</b></h3>
             '''.format(loc)   

m = folium.Map(location=[27.783889, -97.510556],
               zoom_start=12)

m.get_root().html.add_child(folium.Element(title_html))

m.save('map-with-title.html')
m
