Simple Javascript Web App (Google Map)

We need you to develop a single-page application featuring a map for one of our customer. You need to add additional functionality to this application, like: map markers to identify popular locations or place, a search function to easily discover these locations, and a listview to support simple browsing of all locations. You will then research and implement third-party APIs that provide additional information about each of these locations (such as StreetView images, Wikipedia articles, Yelp reviews, etc). All informations will be forwarded to you in a second step.
