How to get AmCharts Maps Drill-Down To Work

The below demo map is perfect for what I need however there are 2 things that I've been trying to do and can't figure out how:

1. I cannot figure out how to add another location in a different city. So the demo shows San Diego with 4 locations, I would also like to add New York with 3 locations and Florida with 2 locations. How do I can't figure out how to add that to the js code.
2. http://www.amcharts.com/tips/map-marker-drill-down/

[list=2]Also, after the user drills down and sees the multiple locations within the city, I would like to add a URL that will take the user to a specific page, like this (http://www.amcharts.com/tips/map-zoom-first-click-marker-go-specific-url-next-click/) but I would like it to open in a new browser if possible.[/list]

Any help will be appreciated. Thanks!
