Based on your description of the diagram, it sounds like the white balls (atoms) are connected by rods representing bonds to the larger red ball (possibly another atom or a central atom in a molecule). The presence of "waves of green lines" running from white balls to the nearest red ball suggests some form of attractive interaction.
If the white balls represent nonmetal atoms and the connections are strong, the most likely type of bonds depicted in your diagram could be covalent bonds. Covalent bonds involve the sharing of electrons between atoms, typically nonmetals, and are represented visually in diagrams by lines.
If we assume the description metaphorically captures aspects of atomic interactions similar to hydrogen bonding (which involves weaker attractions between molecules), the answer could point to hydrogen bonds as well. However, since covalent bonds generally involve a stronger direct connection between atoms than hydrogen bonds, covalent bonds would be the more appropriate response based on standard interpretations of molecular structures with fewer ambiguities.
Thus, the most likely type of bonds shown in your diagram are covalent bonds.
