Phillip, VisAD provides the necessary functions for your spreadsheet. I don't know if there are other systems that would do it better. It is true that VisAD provides lots of functions you don't need, and like any rich-functionality system it can be difficult to master. Your best bet is to dig into it a bit, as well as digging into other candidate systems, and determine which you prefer.

What I'm looking to create is something like a standard number-based spreadsheet with added functions for direct manipulation, image content in cells, and some data visualization - but that is not the major function. Do you think VisAD is a good choice for doing this? the example applications seem to stress on data visualization. - Phillip -- An Excellent Credit Score is 750 See Yours in Just 2 Easy Steps!
