What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image is a black and white line drawing featuring multiple figures and shapes. There are seven primary figures, all of which are stylized and resemble cartoonish pigs, encased within heart-shaped borders. Each pig has different features but generally includes eyes, a round nose, and limbs protruding from a notably oval body. The limbs are simplified, with lines indicating legs and arms. The pigs display various expressions and orientations within the hearts. Across the image, there are also several smaller heart shapes without any figures inside them. The overall composition is spread across a single horizontal plane, with clear boundaries around each heart and figure, suggesting individual entities or characters within a larger theme.
