m.add_markers(markers=[[40, -100], [35, -110]], shape="circle")

Customize circle markers.

In [6]:

m.add_markers(
    markers=[[40, -100], [35, -110]],
    shape="circle",
    radius=20,
    color="red",
    fill_color="#3388ff",
    fill_opacity=0.5,
)

m.add_markers( markers=[[40, -100], [35, -110]], shape="circle", radius=20, color="red", fill_color="#3388ff", fill_opacity=0.5, )

Add country polygons to the map.

In [7]:

m = leafmap.Map()
countries = "https://open.gishub.org/data/world/countries.geojson"
m.add_geojson(countries, layer_name="Countries", info_mode=None)
m

m = leafmap.Map() countries = "https://open.gishub.org/data/world/countries.geojson" m.add_geojson(countries, layer_name="Countries", info_mode=None) m

Add circle markers with popups to the map.

In [8]:

m.add_data(url, column="population", cmap="Blues", marker_radius=5, layer_name="Cities")

url = "https://open.gishub.org/data/world/world_cities.geojson" m.add_data(url, column="population", cmap="Blues", marker_radius=5, layer_name="Cities")
