PrintIn this lesson, you built your first Google Maps customization. Even the simple map that you created involves a number of different technologies (HTML, XML, XHTML, the HTML Document Object Model, and JavaScript) and it is important that you have a firm understanding of this material before moving on. If you skipped over the w3schools tutorials referenced in the lesson, be sure to go back and complete them.
In Lesson 4, you'll see how to spice up the rather dull product of Lesson 3 by adding navigation and map type controls, opening info windows when the user clicks on a marker, using a custom marker icon, and adding line and polygon overlays.
