I've never used TikZ and certainly not for drawing graphs. Based on your experience with TikZ, would you say I shouldn't try to draw the graph below with it?
Look at the combinations of lines consisting of an arrowed line, a dotted line and a line ending with a black dot (e.g. there's one between A1 and Q1). I assume that I could draw such by drawing 3 different lines, but can I keep them aligned so that they would appear as a straight and continuous path? Or will there be visible joints?
I'd prefer simplicity, so it might be easiest to somehow group lines together, but is that even possible?
