--stars. So if you were going to map a three dimensional region of a galaxy (say a 20ly radius sphere or something), how would you go about indicating height and such. I imagine the best bet would be to pick a coordinate system and then draw the whole thing in perspective so that your "flat" (i.e. 0) plane diminished into the distance at least somewhat. Might you use size to indicate distance from the "viewer"? Color for star type, political allegiance, or population/importance (or whatever else might be relevant to your map)? Let's hear some thoughts. This is entirely hypothetical, so don't worry or anything, if you don't have an example.
