## Ejemplo
|
|
|
|
```python
|
|
gj = valhalla_isochrone(lat=40.4168, lon=-3.7038, minutes=15)
|
|
if gj:
|
|
print(f"{len(gj['features'])} features en la isócrona de 15 min")
|
|
```

## Notas
|
|
|
|
Extraida de `_fetch_isochrone_polygon` en `recomendador_centros.py`. Parametrizada para ser reutilizable (el original usaba constantes globales VALHALLA_URL, CONCURRENCY, TIMEOUT_S). Retorna None ante cualquier excepcion.
