I started calling this DataViz driven Development but I am more interested in DataViz of the application state, than code statistics. I am a big debugger fan, however, it falls down when debugging things that are not well represented as assignments. For example, spatial problems are better visualised with maps (rendered as images), not lists of features with numeric coordinates. Here DataViz can bridge the legibility gap between the internal representation and something a programmer can quickly grasp to find bugs.

So in my opinion the best place for going beyond text in programming is by adding custom DataViz to express program state at runtime.
