How I use maps APIs in Pydantic, Jupyter?
Answer
To install bibl.
import pandas as pd
import folium
from folium.plugins
import MarkerCluster
import base64
Pre-carrega ícones em base64 (cache)
icon_cache = {}
for brand_key, filename in icon_mapping.items():
icon_path = ICONS_DIR / filename
if icon_path.exists():
with open(icon_path, 'rb') as f:
img_data = base64.b64encode(f.read()).decode()
ext = icon_path.suffix.lower()
mime = 'image/jpeg' if ext in ['.jpg', '.jpeg'] else 'image/png'
icon_url = f'data:{mime};base64,{img_data}'
icon_cache[brand_key] = folium.CustomIcon(
icon_url,
icon_size=(32, 32),
icon_anchor=(16, 32),
popup_anchor=(0, -32)
)
def color_for_brand(b):
s = str(b or "")
for k, v in palette.items():
if k.lower() in s.lower():
return v
return "#555555"
def icon_for_brand(b):
s = str(b or "")
for k in icon_cache.keys():
if k.lower() in s.lower():
return icon_cache[k]
return None
Mapa base
m = folium.Map(
location=[df[lat].mean(), df[lon].mean()],
zoom_start=11,
tiles="CartoDB positron"
