Info Windows

  • This webpage provides a basic example of using Google Maps to display a marker with an info window.

  • When clicked, the marker for Uluru (Ayers Rock) in Australia displays an info window containing details about the landmark.

  • The sample code demonstrates how to implement this functionality using either JavaScript or TypeScript.

  • The webpage offers links to documentation, live demos, and instructions for running the sample locally.

This example displays a marker at the center of Australia. When the user clicksthe marker, an info window appears.
