Title: Add semicolon delimiter to d3.csv2

In some countries it is very common to write the decimal point as a
comma instead of period, even the default csv file generated from
softwares like Excel and Numbers in countries like Brazil uses
semicolon instead of comma.

I've taken the same approach to name (csv2) as R.
