This project retrieves data from the Yelp API for restaurants by location and by category. It turns that data from a series of json files into csv files at a variety of levels of aggregation---search-level, restaurant-level, city or zip-code level---to facilitate mapping, visualization, and analysis.
You'll need an API key saved in src/yelp.yml to use this code.
