The Wikipedia article [0] has a nice animation [1] of the trajectory through the inner solar system, sourced from this [2] 3D interactive viewer (press “Plot Object” and then drag the slider below “Change Time Speed”).

Thanks for [2]. The wikipedia animation makes it look roughly in-plane, but the 3D viewer shows that it is very much not.
