PrintIn this lesson, you've seen how to modify the Google Maps user interface, open info windows when markers are clicked, implement a custom marker icon, and code the addition of line and polygon overlays. To this point, we've only dealt with a small number of points and have been able to hard-code their locations in our JavaScript code.
In the next lesson, you'll learn how to handle a larger number of markers in a more realistic way by storing their attributes in an XML file. You'll also learn how to add a sidebar that lists the names of your markers and how to use the API's address geocoder.
