Leaflet map

from ipyleaflet import Map, Heatmap
from random import uniform
import time

def create_random_data(length):
    "Return a list of some random lat/lon/value triples."
    return [[uniform(-80, 80),
         uniform(-180, 180),
         uniform(0, 1000)] for i in range(length)]

m = Map(center=[0, 0], zoom=2)
m

Now we add a heatmap:

heat = Heatmap(locations=create_random_data(1000), radius=20, blur=10)
m.add_layer(heat)

Finally, we add some animation to our heatmap:

for i in range(100):
    heat.locations = create_random_data(1000)
    time.sleep(0.1)
