Help creating interactive map

[DciplesHeat]

Hello,
Im trying to make a map, that looks like this one http://www.jetblue.com/wherewejet/
And Im wondering how they make that map so interactive like that

Im going to attempt to make one similar, and I wanted to see if anyone could point me in the right direction of some tutorials that would help me get started

Thanks in advance :-)

Best Regards,
