"""

import streamlit as st
from streamlit_folium import st_folium
from folium.plugins import Draw
import folium

m = folium.Map(location=[40.7128, -74.0060], zoom_start=12)
Draw(export=True).add_to(m)
output = st_folium(m, width=700, height=500)

if output and 'last_active_drawing' in output:
    geojson_data = output['last_active_drawing']
    st.write("Geofence drawn:", geojson_data)
