Visual representations are not terribly hard to come by in this day any age. It's almost trivial to write a little script that can visualize your tree data-structures or relations. Plenty of good environments allow us to mingle all kinds of data. I'm more interested in programs that understand programs and their run-time characteristics. It'd be nice to query a system that could predict regressions in key performance characteristics based on a proposed change (something like a constraint propagation solver on a data-flow graph of continuous domains); even in the face of ambiguous type information. Something like a nest of intelligent agents that can handle the complexity of implementation issues in concert with a human operator. We have a lot of these tools now but they're still so primitive.
