Prior to quantum theory, we only knew the geometry and patterns of those bonds by experiment.
Prior to quantum theory, chemistry had no general theory to explain why atomic bonds are shaped as experiment revealed them to be. We didn't really know the reasons why bonds behaved as we found them to behave. Stick-and-ball models are perfectly fine to use to tell us the shapes of molecules. As to what's being shown in the image, what you are seeing is are the places where electrons are most likely to be found. I like to think of the balls as cartoon beehives.
