Lab Google Mars (AJAX)

1. Observe how Google Mars loads the map and does the zooming. Is the data downloaded once
for all or retrieved on demand?

A: retrieved on demand

2. HTML alone cannot perform the functions of Google Mars. So find out which code in the HTML
source does the map things.

Hints: You may use Nvu to determine what HTML tags are for what.
