a few days ago I saw the new Bing mall's maps. Link here
I'm a newbie and I was very impressed, so I was wondering just how did they do these internal maps. It 's a simple mashup or similar? Or use some special JS library?
There are JS libraries (or other languages too) that gives the ability to create internal maps of buildings outside of google maps / bing maps? Like drawing a real internal map of house or other buildings (vector or not) by JS functions, variables and data ....
Thanks for your help!
PS: sorry for my english
