In this article, I'll demonstrate the basic concept of content aggregation (aka mashups). I'll provide code to utilize the services of three different Web based APIs. Specifically Yelp, Map Quest, and Google Maps. The finished product will be a displayable/embeddable map for a requested location. Pins will be set into the map that show points of interest based on user entered criteria. Each pin will display its information in a pop-up when the user hovers over it. A demo of the completed project can be found here.
