"D3’s d3.csv function. We don’t need the total column that the dataset uses, so we’ll use the $select parameter to filter down to the four columns we really care about. 
We’ll also use the $where parameter to only get ridership after 1999, and the $$app_token parameter to pass our application token."

++ uses parameters in D3 instead of return function data.

++ set up svg. then uses data from callback to fill element.
