Large datasets will often require you to make a background request to a server to fetch data. Using D3's AJAX methods, we can easily request data to use in our visualizations. 
• Read documentations about the Observatory of Economic Complexity's (OEC) API 
• Determine which data call to use 
• Use the D3.json() method to fetch data from the server 
• Merge 2010 and 2011 data calls to the OEC API
