You could use NMatrix instead of NArray and Rubyvis for vi= sualization. There's a GUI front-end, SciRuby::Plotter, but I'm not= sure it's working on Windows as I'm not the maintainer.

Sci= Ruby can't compete with R or the Python stack yet, but it should be eno= ugh for a job like this. :)

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

=A0 C:\>ripl -rnarray
=A0 DL is deprecated, please use Fiddle

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/pan= das/numpy/scipy/matplotlib/ipython for stats and data analysis. I've no= t looked at sciruby in awhile, but I suspect windows support is not a prior= ity.
