Yes, ruby networking and the fantastic multi-platform narray gem will take you far

  C:\>ripl -rnarray
  DL is deprecated, please use Fiddle
  >> RUBY_DESCRIPTION
  => "ruby 2.0.0p102 (2013-04-03 revision 40075) [i386-mingw32]"
  >> a = NArray[3,4,20.0]

  => 9.0

but I'm not familar with data vis for ruby that also works on windows. I primarily use windows and arch and it's hard to beat R and python/pandas/numpy/scipy/matplotlib/ipython for stats and data analysis. I've not looked at sciruby in awhile, but I suspect windows support is not a priority.
