A Javascript application to build a route using the Google Maps APIs and generate the elevation chart real time (as the route is being modified). The application has support for unlimited number of waypoints.

The application uses the Google Elevation API: https://developers.google.com/maps/documentation/elevation/intro , for which you need an API key: https://developers.google.com/maps/documentation/elevation/get-api-key

Since the application runs fully on the client side, the API key will not be sent to any server other than the Google elevation API.
