Maps of Conceptual Space

In this course we primarily focus on maps of physical space since this is what constitutes most maps. It occurred to me in one of my other classes that maps don't necessarily have to represent physical space. In my kinetics class my professor was drawing a block flow diagram outlining the steps of a reactor design algorithm and I thought to myself, "hey! that's a map!" It used symbols to convey information and was even intended to give directions to solving a problem just as maps can provide directions to solving the problem of getting somewhere. I thought it was pretty cool that maps can be extended beyond what immediately comes to mind when hearing the word.
