The Google Maps tool allows you to embed an interactive Google map into any page of your website.
Click the 'Add content' button on the page you would like to insert the map and select the 'Google Map' content type. A dialog form similar to the one above will be shown. You can specify the dimensions of the map and the initial zoom level (people can zoom in/out at will). Then simply type or paste the full address for the map into the field and click 'Save'.
Below is an actual Google Map inserted using this tool. It can be dragged, zoomed in/out, etc.:
