How to read in CSV with d3 v4?

Question

I'm just having a little trouble understanding the documentation for CSV Parse with D3. I have now:

d3.parse("data.csv",function(data){
    salesData = data; 
});

But I keep getting the error:

Uncaught TypeError: d3.parse is not a function

What should it look like? I'm just a little confused, and the only examples that I could find are something like this .

I also tried something like:

d3.dsv.parse("data.csv",function(data){
    salesData = data; 
});

and received:

Uncaught TypeError: Unable to read 'parse' property from undefined

Why is this happening? Any help would be greatly appreciated, thanks!
