This is a Node.js library for generating isochrone maps—areas that represent equal travel times from a given point. It leverages OSRM for routing, Turf for geospatial analysis, and concaveman for creating polygon boundaries. The tool is ideal for developers building applications that require travel-time visualizations, such as urban planning tools, logistics platforms, or location-based services.
