I'm working on adding elements to a report at work that does data visualization on a large scale (the data set is about 1 million data points; it's really not all that impressive of a subject matter, but I can't be terribly specific). The report has all of the "easy" elements I need in it, but now I'm trying to add in the harder elements. My ultimate end goal would be to add in the more complicated data along with system parameters, so I can get a handle on how parameter changes affect the output. I'd love to see Bayes nets and the like make a triumphant entrance at some point. But near as I can tell, I'd be the local expert on all of that, and anything I know about that subject matter I mostly picked up from here.
