How to change the locations

Hi and thanks for sharing your work, it's almost exactly what I need. Is there a method to change the serviceable area? I need something localized for a restaurant that's setting up a delivery service.

I'm thinking I would need to a) change the way it's calling the google chart part or b) strip all the dynamic part and hard-code an array of options although I'm more of a designer than coder.

Thanks for you insights!
