Added the raw budget file as provided on http://opendata.rijksbegroting.nl/. I manually replaced some faulty characters in this csv. The characters which needed to be fixed were "ë" in "Financiën" and "ç" in "Curaçao".
This Perl program converts the raw Dutch budget into two csv files which are used for the visualisation.
The output csv files of data_processing.pl
Adapted the US budget code to work with the Dutch budget data and translated the text.
