You've read the article? Then you must have noticed that the diagram depict a curved orbit for the Voyager while it is close to the Sun and its gravitational influence but switches to a straight line when the Voyager is moving outward toward and between the outer planets it visits. Did the artist decide to switch symbolism mid-drawing? Artistic license is NOT TAKEN with these types of diagrams, accompanying pages of detailed and explicit text. If you imagine that the author, Charles Kolhase, failed to review the diagram prior to publication, especially when his job title includes the word "Planning Office", then you're either naive, inexperienced, or simply not thinking.
