I see now - if I look closely enough, now I can see the blue orbit line for Earth extending off the chart. Thank you, Tom.

No, I think that's really Mercury. I read somewhere that Earth was going to transit the tiny 3' disk of the Sun as viewed from Saturn. The field of view of the figure is 5 degrees. It's too early in the morning for me to do basic trigonometry, but I bet that works out, knowing the diameter of Mercury's orbit.
