: You may be confusing free-fall speed with acceleration. If there was a narrow airless hole going through the Earth, and you fell from the surface into the hole, your speed would indeed be maximized as you passed through the center of the Earth. But that is exactly what you would get if the acceleration was 0 at the center (and then negative, i.e., pulling you in the opposite direction) past the center.
: Now you might argue that if you were at rest at the center of the Earth, you'd be accelerated (in what direction?) faster than the ~9.8 m/s^2 at the surface. (I'd say you're wrong, but ok.) But that's not what the chart shows; it shows how fast you'd fall if you were at rest at the center of the Earth (and at other points) ''in these three models''. You seem to believe that none of these models reflect reality, but that's not only unsourced speculation but not particularly relevant to this article.
