The graphs are really bad. The problem I have is not the continuity, which as you say can help to identify trends, but the huge gap between two real data points. It should be clear what is real data and what is not (for example, using a linespoints graph), it really looks like there were medals won in non-onlympic years. The author focused too much on making beautiful graphs instead of just presenting the data.
