What options did you call the script with? Whatever, your use of  
OptionParser is wrong. You are asking for date options with no  
arguments where you should be asking for arguments:

opts.on("-s", "--startdate", "Determines what start date to use.") do

Should be:

opts.on("-s", "--startdate DATE", "Determines what start date to  
use.") do

And the same for the end date and output options. Check the  
OptionParser docs. There are other bugs in there as well: "ARGV =  
svg" should surely be "d = 'svg'" for instance.
