This came up over breakfast this morning, coincidentally. I start out with a mainly visual representation like a graph, with modules as nodes and edges as interconnections. I'm possibly strange in this regard, but my perception changes as things get more complicated. Once this graph gets sufficiently complicated that it's difficult to represent it as a planar graph (too much edge overlap), I lose the visual representation but can continue to reason about it. What's left isn't particularly visual, nor is it textual... I'm not sure how to explain it really. I end up manipulating this abstract "thing" in my mind, which I can translate (on paper or in code) to a concrete representation after the fact. Anyone else have similar experiences?
