No, when you request the URL, it's supposed to return a CSV file. You provide the URL to D3, and it makes an Ajax request to the URL in order to retrieve the CSV file. See https://github.com/mbostock/d3/wiki/CSV. Looks like you can also pass a CSV string to D3.csv.parse(), so you might be able to just include the CSV content hidden in the HTML and extract the text node and pass it to D3. You might also consider using JSON, which will save D3 the trouble of parsing CSV.
