Why is gravity visualized by putting a heavy object on a flat plane, creating the curved shape, when space is 3D?

Question

Wouldn’t it curve and pull objects in all directions?

Answer 1

It’s difficult to represent the phenomena visually. But yes, gravity does bend space in 3-dimensions. There just isn’t a good way to show it visually.

Or actually a 4-d bend, but I feel like that is getting over the scope of this topic.
