isochrone
Calculate reachable area polygons within a travel-time budget using lat/lon, mode, and minutes. Returns polygon coordinates and area in square meters.
Instructions
Reachable-area polygon within a travel-time budget.
Units: lat/lon in decimal degrees; minutes in minutes; polygon ring
as [lon, lat] pairs; area_m2 in square metres.
Example: isochrone(lat=3.15, lon=101.71, mode="walk", minutes=10)
