Using New Orleans Open Data API to Map Local Businesses with Javascript D3

As a New Orleans company, we love diving into data about our city’s vibrant business ecosystem – and we appreciate that the city government is kind enough to offer us so much of it. The Occupational Business License Data for the Office of Business and External Services offers a window into the local economy that can be beautifully illustrated through Javascript D3 and Leaflet.

(You might not see any data at first. There are over 17,000 businesses in this database, so it takes a second for it all to arrive!)

Due to the type of data available, not all businesses are displayed with names. Some provide a general description instead.
