我想在 folium map 中添加一个图例到下面的代码中

Question

m = folium.Map(location=[39.735,-84.15],zoom_start=10.5)
for idx, row in gdf1.iterrows():
    folium.Marker([row['Latitude'], row['Longitude']], popup=row['Name'], 
icon=folium.Icon(color=row['Colors'])).add_to(m)

This code shows the following output

I want to make a legend that will say the blue marker represent 'other hospitals' and the red marker represent 'dayton'

Answer 1

Please have a look here in this related post Create a Legend on a Folium map

There are two possibilities mentioned:

• using layercontrol with colors (would mean you use multiple MarkerCluster)
• just adding an image as an overlay with your text and color
