To visualize the space curvature related to gravity, there is a model or analogy using an elastic sheet and a weight. A rubber sheet is spanned like a very soft trampoline, and a heavy ball on it creates curvature in the sheet.
In this model, ist there a way to represent gravitational waves?
Dropping a ball on a rubber sheet creates a change in the shape of the sheet. This change does not affect the whole sheet instantly, it propagates from the impact away. Does the propagation have the form of a surface wave? Is that wave somehow analogous to a gravitational wave?
