Angular Map - Routes

The Map component can display routes on the map. The collection of displayed routes is declared in the routes array. You can use the mode property to specify whether a route is for driving or walking.

When copying this demo to CodeSandbox, specify your own apiKey. Our demo keys can be used only on our website.
