So, I've got the graph all set up, now I just need to re-dump the SWF so I can have a transparent line and points of a different color, so it actually looks like a scatter-plot.
Open Flash Charts is pretty buggy and under-documented, but I guess that's why it's free. Shame that it's not got the big enough following for people to actually make commits to it though.
I've figured out a way to serialize my data for the tag recognition. I just have to set up a vendor folder with an init.rb in it to do the includes, and then I'll just Marshall.dump(data) into a text field in the db. Trivial process for getting it back out, and doing a lot of the serialization myself takes some of the rails processing power out of it - I trust my own implementations a lot more than Rails' at this point.
The only thing left to do after that is to clean up how comments are displayed and generated, and then to create a tagging page for 'learning mode.' I still don't know how I'm going to implement LSI yet, but I'll figure out a way to make it work.
